Could you fix this? I'm having the same problem.

Woah, HI. Yea... Not the best solution, but this fixed it

sudo mv /Library/Python/2.6/site-packages/readline* /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/

Thanks! It solves it but breaks ipython.

Oh dear God, provide us with better Python packaging on Mac OS X...

hrm, my ipython seems to be working fine for me. maybe try reinstalling w/ easy_install and if that doesnt work, pip?

Here's a highly-experimental (i.e. tested once, quickly) patch here:

For anyone else who stumbles across this gist when googling:

This issue appears to be fixed in virtualenv's latest source. If I am not mistaken, it uses @acdha's patch.

fitzgen is right: since we were all at the table at PyCon during the sprints, @carljm merged it after a but of testing
