Well, I added a .install file:

https://maemo.org/downloads/product/...6b47bb47b.html

http://idefix.go-nix.ca/nix/pidgin.install

I think this only works on Chinook, because it adds multiple repositories. Also, you cannot install multiple packages from a .install file, so it only installs Pidgin - no sounds, no smileys

But, I guess it's better than nothing ... *shrug*
