Including one thing I've always wanted to be able to do.  If you define
PERL5LIB, you can override the Preferences...Libraries search order for
libraries.  That means you can get your own stuff looked for ahead of the
MacPerl Ä:lib defaults.  Paths should be put in to PERL5LIB as comma
separated full Mac paths.  The path "wherever:MacPerl Ä:lib:" always gets
expanded into
"wherever:MacPerl Ä:lib:MacPPC" and "wherever:MacPerl Ä:lib:" (and I presume
it's "wherever:MacPerl Ä:lib:Mac68K:" or something like that, on 68k
machines), and ":" and "Dev:Pseudo:" always get added on the end by default.

So, for example, when I want to find libwww-perl-5.15 (give me a few days
to construct an installer) and libnet-1.0601 (not ready for prime time)
ahead of the libwww-perl-5.13 and libnet-1.0501 that now come with 5.15r4,
I set PERL5LIB to:

The Black Pits:PERL5LIB:,The Black Pits:Applications:MacPerl Ä:lib:,The
Black Pits:MacPerl_scripts:lib:

and get my usual MacPerl search path reordered the way I want it.
