There's a new version of pytraffic available upstream. As the dependencies have changed (pygtk2 instead of tkinter), I've marked this ~arch, and I'm attaching a new ebuild below.
Created attachment 53388 [details] pytraffic-2.0.ebuild
Bumped on CVS. Just a side note: currently pytraffic only works with pygtk-2.4, so I've restricted the deps.
Good point. Thanks for uploading!
