Gwibber on Debian Lenny - Florijan explains it for Gnome.

He describes everything you need for the identi.ca-/twitter-client: http://www.florijan.net/?p=3

But only as long as you use Gnome as a regular Desktop, but for a thin installation using fluxbox f.ex., I stopped my efforts after I got the python-message: "ImportError: No module named gnome"

OH NOES!

So here I stay with my tkabber and iceweasel-combination.
