Re: Adding to @INC

Mac OS neXt also provides for a file:

$HOME/.MacOSX/environment.plist.  .If it's not present you can create 
it and its hidden directory.  Contents are environment variables that 
you would like defined even if you haven't opened a Terminal.app 
session. AppleScript's do shell script command, for instance will not 
run your startup scripts for your chosen shell.

In environment.plist you can define

PERL5LIB   as   /opt/local/lib/perl5/site_perl/5.8.8

without adding whatever else was in $PERL5LIB.  The result is 
independent of your choice of shell.  Apple has published a note on 
it somewhere. Concatenations to existing environment variables will 
not work.

Watch out for some errant scripts in /etc/ that once overwrote $PATH 
when it was redefined in environment.plist.
