For Mac OS X see README.macosx
Perl under Mac OS Classic has not been supported since before Perl 5.10 (April 2004).
When we say “Mac OS” below, we mean Mac OS 7, 8, and 9, and not Mac OS X.
The port of Perl to Mac OS was officially removed as of Perl 5.12, though the last official production release of MacPerl corresponded to Perl 5.6. While Perl 5.10 included the port to Mac OS, ExtUtils::MakeMaker, a core part of Perl's module installation infrastructure officially dropped support for Mac OS in April 2004.
Perl was ported to Mac OS by Matthias Neeracher <firstname.lastname@example.org>. Chris Nandor <email@example.com> continued development and maintenance for the duration of the port's life.
