I'm looking for a Python IDE that can help me easily locate and manage and use the libraries on my system (Ubuntu). Specifically Twisted.
Code completion is important including the symbols I import.
(I've so far had a look at PyDev as well as OpenKomodo, but while both offer code completion for default Python concepts, I wasn't able to get either to import Twisted into my project and was thus getting reference errors.)
Usual disclaimer: I don't like EMACS or vi, please, nothing regarding those.
Using Wing IDE with Twisted discusses how to debug twisted using their IDE - although unfortunately WingWare is not free.
Are you sure you have given PyDev a fair look? It seems to be the most popular Python IDE, and I have always had good experiences with it in the past.
