Gadu-Gadu is an IM protocol popular in Poland. You can find more about it
[here](http://www.gadu-gadu.pl) (website in Polish).
### I compiled Pidgin from source. Why doesn't it have Gadu-Gadu support?
We use an external libgadu. Install your distro's `libgadu-dev` (Debian-based
systems) or `libgadu-devel` (RPM systems) and rebuild Pidgin (making sure to
re-run `./configure` in the top of the source tree).
