in reply to how is @INC set up

I can't add much to what ikegami already said, but you might also wish to look at:

If you just want to view the contents of @INC, the following script might be useful:

#!/usr/local/bin/perl -w
# Display the contents of @INC 
warn "\@INC is: ", join(' ', @INC), "\n";
