Q. I run setup.py and see this error:

$ sudo python setup.py egg_info

A. This seems to be a known bug in setuptools which pops up if you have any uncommitted directory when you run setup.py. As a workaround, you need to either commit or temporarily revert any directories marked as 'A' by Subversion ('M' are ok).
