Yahoo changed their IM protocol so if you use that protocol under pidgin, you'll need to compile pidgin 2.5.7 Carrier (the pidgin fork) hasn't included the fixes yet so it's useless with Yahoo, I had to go back to using pidgin. Pidgin is updated often enough that it's one of the few things I'd recommend compiling on ones own to keep it up to date, and in fact, it was one of the few things I did keep up to date on the PS2 Linux kit.
