On a new Fedora 19 install, I began updating eggs with pip-python. When I got to: # pip-python install --upgrade urlgrabber fpconst distribute chardet boto It (first) failed, then nothing would work after that; everything errors with the message below now.

ImportError: No module named pkg_resources

# pip-python freeze | cut -d = -f 1 | xargs -n 1 pip-python search | grep -B2 'LATEST:'
