I've created a warpin package for Perl, which can be found at http://smedley.info/os2ports
The Warpin installer utilises the path-rewrite functions available in libc, together with klibccfg - available from ftp://ftp.netlabs.org/incoming/klibccfg.wpi to make Perl work much nicer. Set statements like 'set PERLLIB_PREFIX' are no longer required.
Any feedback appreciated!
Cheers,
Paul.
