in reply to how to include a directory in @INC?
For every directory you wish to "permanently" add to @INC, create a symlink from the directory in your perl's site_perl ( eg, /usr/local/lib/perl5/site_perl ). Perl will cross the symlink when searching the paths.
This suggestion is expected to be taken at your own risk. DO NOT blame me if somebody figured out how to exploit this from your webserver.
