Super Search is your friend here in the Monastery. :-) Here are several nodes that deal with @INC issues (handy to keep around for future reference, as this issue occurs frequently):

Require a script not found in @INC array
How to change @INC permanently?
How is the default @INC constructed?

Definitely, though, take runrig's excellent advice and ask Randy Kobes - I got a turnaround of less than 24 hours on one of my requests and it installed seamlessly. :-)

HTH,
