+=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.

Since you don't have a C compiler, you're doomed and your vendor
should be sacrificed to the Sun gods. But that doesn't help you.
first. Consult the Usenet FAQs for your operating system for
information on where to get such a binary version.
-=head2 I copied the Perl binary from one machine to another, but scripts don't work.
+You might look around the net for a pre-built binary of Perl (or a
+C compiler!) that meets your needs, though:
+
+For Windows, Vanilla Perl ( http://vanillaperl.com/ ) and Strawberry Perl
+( http://strawberryperl.com/ ) come with a
+bundled C compiler. ActivePerl is a pre-compiled version of Perl

+
+For Sun systems, SunFreeware.com provides binaries of most popular
+applications, including compilers and Perl.

+=head2 I copied the perl binary from one machine to another, but scripts don't work.
That's probably because you forgot libraries, or library paths differ.
You really should build the whole distribution on the machine it will
One simple way to check that things are in the right place is to print out
the hard-coded @INC that perl looks through for libraries:
- % perl -e 'print join("\n",@INC)'
+ % perl -le 'print for @INC'
If this command lists any paths that don't exist on your system, then you
may need to move the appropriate libraries to these locations, or create

=head2 What are the Perl newsgroups on Usenet? Where do I post questions?
-The now defunct comp.lang.perl newsgroup has been superseded by the
-following groups:
+Several groups devoted to the Perl language are on Usenet:
+
+ 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.

+The first (and for a long time, only) periodical devoted to All Things
+Perl, I<The Perl Journal> contains tutorials, demonstrations, case
+studies, announcements, contests, and much more. I<TPJ> has columns
+on web development, databases, Win32 Perl, graphical programming,
+regular expressions, and networking, and sponsors the Obfuscated Perl
+Contest and the Perl Poetry Contests. Beginning in November 2002, TPJ
+moved to a reader-supported monthly e-zine format in which subscribers
+can download issues as PDF documents. In 2006, TPJ merged with Dr.

same question at some point on c.l.p.m. It requires some time and patience

However, these answers may not suffice for managers who require a
purchase order from a company whom they can sue should anything go awry.
Or maybe they need very serious hand-holding and contractual obligations.

+found an actual bug.
-=head2 Where do I send bug reports?
+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
+C<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.
-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 .
+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 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.
