I'm using Pidgin on Chinook, and replaced my libpurple0_2.5.1-0nix2 by your hacked one. Unfortunately it messes up my contacts completely, e.g. I don't see any of my Jabber contacts any more etc. It seems it's not compatible with my revision of Pidgin. Fortunately, reverting to the old library brings back my contacts, so I just disabled ICQ for now.
