I'm having problems using NanoMsg. I was using default sockets before but then someone pointed out that this was a bad idea. So I searched to get a better package and found NanoMsg. When I tried importing I got this error:

I had installed pyquery with "easy_install pyquery" and this was causing this error.
I removed it and then installed it from https://github.com/gawel/pyquery with python setup.py install and now it's working.
I have a Python app that works fine. Now I use py2exe to create a windows executable of this app, however the resulting exe fails with complain that it lacks the configobj module
Traceback (most recent call last):
File "file1.py", line 1, in <module>

ImportError: No module named configobj
Line 10 in file2.py is merely from configobj import ConfigObj
I tried to explicitly add configobj to the list of packed modules by specifying -i configobj argument, but then the py2exe run fails with the similar error:

What am I doing wrong ?
Reinstalling configobj from source fixed the problem. Damn me if I know why

Should be easy to fix: just upgrade your install of django-celery.
