They aren't the same package. The perl-gtk2 api changed. I wrote a summary of my cooker-ppc experience abotu a month ago and posted packages I found to be lacking here:

The summary in in this list's archives, as well as the PPC forum on mandrakeclub.
Thanks for the hint and the packages. I'll let you know about the result of my migration to cooker.
