Where the heck is GAP??? (GIMP ANIMATION PACKAGE)

It's such a wonderful thing and I found an old topic about it, but I am worried it won't work for gimp2.6.7.

Heres a page where you can download it from: http://www.gimp.org/
and Here is the page on how to use it:http://www.gimp.org/tutorials/Using_GAP/

Please make a portable version. I really want to use it.
