GTk Install

[Gallagher Timothy-TIMOTHYG <TIMOTHYG motorola com>]

        I am new to GTK and have installed the GTK2 ppm from the repository;
everything looks to be installed fine.  I tried  to do a simple gtk example
from the Perl-GTK tutorial from  Stephen Wilhelm.  This is the "GoodBy
world" example but I keep getting errors that looks like I do not have
perl-gtk installed correctly.  Here is the error that I get: 

"Can't locate Gtk.pm in @INC (@INC contains: c:/Perl/lib c:/Perl/site/lib .)
at
.pl line 1.
BEGIN failed--compilation aborted at a.pl line 1."

Can someone please help?

Thanks
