If you have C<man> installed on your system, and you installed perl
manpages, use something like this:

If you have some WWW browser available, you can build B<HTML> docs.

Alternatively you may be able to get these docs prebuilt from C<CPAN>.

Users of C<Emacs> would appreciate it very much, especially with
C<CPerl> mode loaded. You need to get latest C<pod2info> from C<CPAN>,
or, alternately, prebuilt info pages.

Here we discuss how to build Perl under AmigaOS.
-=head2 Prerequisites

You need to have the latest B<ixemul> (Unix emulation for Amiga)
from Aminet.
-=head2 Getting the perl source
+=head2 Getting the Perl Source for AmigaOS
You can either get the latest perl-for-amiga source from Ninemoons
and extract it with:
or get the official source from CPAN:
- http://www.perl.com/CPAN/src/5.0
+ http://www.cpan.org/src/5.0
Extract it like this
is normal and expected. (There is a conflict with a similarly-named file
F<configure>, but it causes no harm.)

+=head1 PERL 5.8.0 BROKEN IN AMIGAOS
+
+As told above, Perl 5.6.1 was still good in AmigaOS, as was 5.7.2.
+After Perl 5.7.2 (change #11423, see the Changes file, and the file
+pod/perlhack.pod for how to get the individual changes) Perl dropped
+its internal support for vfork(), and that was very probably the step
+that broke AmigaOS (since the ixemul library has only vfork).
+The build finally fails when the ext/DynaLoader is being built, and
+PERL ends up as "0" in the produced Makefile, trying to run "0" does
+not quite work. Also, executing miniperl in backticks seems to
+generate nothing: very probably related to the (v)fork problems.
+B<Fixing the breakage requires someone quite familiar with the ixemul
+library, and how one is supposed to run external commands in AmigaOS
+without fork().>
