The only bit of advice I can give you without seeing any errors or knowing what your are using to compile, is make sure you have all the relevant use statements at the start of your code. the following is from the Perl2exe Manpage...

8. "Can't locate somemodule.pm in @INC at myscript.pl line 1" error message

If you get an error message like the one above, you can force the missing module to be compiled into the exe by adding a line like one of the following to your script:

use somemodule;

Or if the message is "Can't locate Foo/Bar.pm in ...":

use Foo::Bar;

This is what catches me most times..;)
