I'm sorry about that - I guess I should have been more explicit. Cart::Validate is a different file. I've got two files:

/path/path/modtest.pl
/path/path/lib/CART/Validate.pm

modtest.pl is pathed correctly to CART::Validate (using "use lib './lib';") to the module since I can get the version number out. Thanks for taking the time to help with this.
