Piggies. Sorry about that. Here you go (with one long line shortened, 
and some spurious POD markup removed from the hints file):

 This document describes how to build Perl 5 on Power MachTen systems,
 and discusses a few wrinkles in the implementation.

+B<Power MachTen is not supported by versions of Perl later than
+5.6.x.>
+If you wish to build a version from the 5.6 track, please
+obtain a source distribution from the archive at
+L<http://cpan.org/src/5.0/> and follow the instructions in its
+README.machten file.

+MachTen is no longer supported by its developers, Tenon Intersystems.
+A UNIX environment hosted on Mac OS Classic, MachTen has been
+superseded by Mac OS X and by BSD and Linux implementations for Macintosh
+hardware.
+The final version of Power MachTen, 4.1.4, lacks many features found in
+modern implementations of UNIX, and has a number of bugs.
+These shortcomings prevent recent versions of Perl from being able to use
+extensions on MachTen, and cause numerous test suite failures in the
+perl core.
+
+In September 2003, a discussion on the MachTen mailing list determined
+that there was no interest in making a later version of Perl build
+successfully on MachTen.
+Consequently, support for building Perl under MachTen has been suppressed
+in Perl distributions published after February 2004.
+The hints file, F<hints/machten.sh>, remains a part of the
+distributions for reference purposes.
