I'm using Aptana Studio 3 beta which comes with Pydev, everything appears to be working apart from I can't import poplib which is part of the standard library.
I added poplib to the Forced Builtins and it seems to prevent it marking it as an error but completions don't work. Am I doing this right? Shouldn't everything in the standard library just work?
Edit: I have the same problem with random as well
When I switched to the default system interpreter the problem went away, the virtualenv I was using must have been corrupt somehow.
