Comment 20 for bug 349837

Why is this bug marked as a duplicate of #410098? It's not. The bug here is that the CalendarServer ubuntu package is broken and won't install. That other bug has to do with the Nevow package being broken in a completely different way, and they are related to different underlying problems. CalendarServer requires its own version of Twisted (one which includes twisted.web2.dav, which is not currently on trunk), which is why it doesn't work, but Nevow's debian package is just interacting with the system version of Twisted improperly.

Zooko: Twisted's "plugins" directory is indeed a Python package. Why do you say it isn't? It's a python package which contains modules from several different uh, "things" (what python would call "distributions" and ubuntu would call "packages").
