+all known and current Unix derivatives are supported (perl's native
platform), as are other systems like VMS, DOS, OS/2, Windows,
-QNX, BeOS, and the Amiga. There are also the beginnings of support
-for MPE/iX.
-
-Binary distributions for some proprietary platforms, including
-Apple systems, can be found http://www.perl.com/CPAN/ports/ directory.
-Because these are not part of the standard distribution, they may
-and in fact do differ from the base Perl port in a variety of ways.
-You'll have to check their respective release notes to see just
-what the differences are. These differences can be either positive
-(e.g. extensions for the features of the particular platform that
-are not supported in the source release of perl) or negative (e.g.
-might be based upon a less current source release of perl).
-
-=head2 How can I get a binary version of Perl?
-
-If you don't have a C compiler because your vendor for whatever
-reasons did not include one with your system, the best thing to do is
-grab a binary version of gcc from the net and use that to compile perl
-with. CPAN only has binaries for systems that are terribly hard to
-get free compilers for, not for Unix systems.

- http://www.perl.com/CPAN/ports/
-
-Someone looking for a Perl for Win16 might look to Laszlo Molnar's djgpp
-port in http://www.perl.com/CPAN/ports/msdos/ , which comes with clear
-installation instructions. A simple installation guide for MS-DOS using
-Ilya Zakharevich's OS/2 port is available at
-http://www.cs.ruu.nl/%7Epiet/perl5dos.html

That's probably because you forgot libraries, or library paths differ.

- % perl -e 'print join("\n",@INC)'

may need to move the appropriate libraries to these locations, or create
-symbolic links, aliases, or shortcuts appropriately. @INC is also printed as

-=head2 What are the Perl newsgroups on Usenet? Where do I post questions?
+Several groups devoted to the Perl language are on Usenet:
-The now defunct comp.lang.perl newsgroup has been superseded by the
-following groups:
+ comp.lang.perl.announce Moderated announcement group
+ comp.lang.perl.misc High traffic general Perl discussion
+ comp.lang.perl.moderated Moderated discussion group
+ comp.lang.perl.modules Use and development of Perl modules
+ comp.lang.perl.tk Using Tk (and X) from Perl
- comp.lang.perl.announce Moderated announcement group
- comp.lang.perl.misc Very busy group about Perl in general
- comp.lang.perl.moderated Moderated discussion group
- comp.lang.perl.modules Use and development of Perl modules
- comp.lang.perl.tk Using Tk (and X) from Perl
+Some years ago, comp.lang.perl was divided into those groups, and
+comp.lang.perl itself officially removed. While that group may still
+be found on some news servers, it is unwise to use it, because
+postings there will not appear on news servers which honour the
+official list of group names. Use comp.lang.perl.misc for topics
+which do not have a more-appropriate specific group.
- comp.infosystems.www.authoring.cgi Writing CGI scripts for the Web.
+There is also a Usenet gateway to Perl mailing lists sponsored by
+perl.org at nntp://nntp.perl.org , a web interface to the same lists
+at http://nntp.perl.org/group/ and these lists are also available
+under the C<perl.*> hierarchy at http://groups.google.com . Other
+groups are listed at http://lists.perl.org/ ( also known as
+http://lists.cpan.org/ ).
-There is also Usenet gateway to the mailing list used by the crack
-Perl development team (perl5-porters) at
-news://news.perl.com/perl.porters-gw/ .
+A nice place to ask questions is the PerlMonks site,
+http://www.perlmonks.org/ , or the Perl Beginners mailing list
+http://lists.perl.org/showlist.cgi?name=beginners .
+
+Note that none of the above are supposed to write your code for you:
+asking questions about particular problems or general advice is fine,
+but asking someone to write your code for free is not very cool.
=head2 Where should I post source code?
You should post source code to whichever group is most appropriate, but

=head2 Perl Books
-A number of books on Perl and/or CGI programming are available. A few of

-Christiansen maintains a list of these books, some with extensive
-reviews, at http://www.perl.com/perl/critiques/index.html .
-
-The incontestably definitive reference book on Perl, written by
-the creator of Perl, is now (July 2000) in its third edition:

- 0-596-00027-8 [3rd edition July 2000]
- http://www.oreilly.com/catalog/pperl3/
- (English, translations to several languages are also available)
-
-The companion volume to the Camel containing thousands
-of real-world examples, mini-tutorials, and complete programs
-(first premiered at the 1998 Perl Conference), is:
-
- The Perl Cookbook (the "Ram Book"):
- by Tom Christiansen and Nathan Torkington,
- with Foreword by Larry Wall
- ISBN 1-56592-243-3 [1st Edition August 1998]
- http://perl.oreilly.com/cookbook/

- by Randal Schwartz and Tom Christiansen
- with Foreword by Larry Wall
- ISBN 1-56592-284-0 [2nd Edition July 1997]
- http://www.oreilly.com/catalog/lperl2/
-
-Despite the picture at the URL above, the second edition of "Llama
-Book" really has a blue cover and was updated for the 5.004 release
-of Perl. Various foreign language editions are available, including
-I<Learning Perl on Win32 Systems> (the "Gecko Book").
-
-If you're not an accidental programmer, but a more serious and possibly
-even degreed computer scientist who doesn't need as much hand-holding as
-we try to provide in the Llama or its defurred cousin the Gecko, please
-check out the delightful book, I<Perl: The Programmer's Companion>,
-written by Nigel Chapman.

+First, ensure that you've found an actual bug. Second, ensure you've
+found an actual bug.
-See also www.perl.com for updates on tutorials, training, and support.
+If you've found a bug with the perl interpreter or one of the modules
+in the standard library (those that come with Perl), you can use the
+L<perlbug> utility that comes with Perl (>= 5.004). It collects
+information about your installation to include with your message, then
+sends the message to the right place.
-=head2 Where do I send bug reports?
+To determine if a module came with your version of Perl, you can
+use the C<Module::CoreList> module. It has the information about
+the modules (with their versions) included with each release of Perl.
-If you are reporting a bug in the perl interpreter or the modules
-shipped with Perl, use the I<perlbug> program in the Perl distribution or
-mail your report to perlbug@perl.org .
+If C<Module::CoreList> is not installed on your system, check out
+http://perlpunks.de/corelist .
-If you are posting a bug with a non-standard port (see the answer to
-"What platforms is Perl available for?"), a binary distribution, or a
-non-standard module (such as Tk, CGI, etc), then please see the
-documentation that came with it to determine the correct place to post
-bugs.
+Every CPAN module has a bug tracker set up in RT, http://rt.cpan.org .
+You can submit bugs to RT either through its web interface or by
+email. To email a bug report, send it to
+bug-E<lt>distribution-nameE<gt>@rt.cpan.org . For example, if you
+wanted to report a bug in C<Business::ISBN>, you could send a message to
+bug-Business-ISBN@rt.cpan.org .
-Read the perlbug(1) man page (perl5.004 or later) for more information.
+Some modules might have special reporting requirements, such as a
+Sourceforge or Google Code tracking system, so you should check the
+module documentation too.

-The perl.com domain is owned by Tom Christiansen, who created it as a
