<I wrote a perl script that runs off of the perl5.8.5 version installed with the MSC software package. I tried running the same script with perl5.12.4 but I am getting the following errors.

Can't locate loadable object for module Tk::Event in @INC (@INC contai

I copied the Tk.pm and additional folders and files into the 5.12.4 structure and then received the following error.

Does anyone know if there's a compatibility issue with tk from one perl version to another? Thank you!
