Open Stack

FASCINATING (I was asking because I know that Salvatore had problems
using easy_install)

I tested by doing:

pip install
http://tarballs.openstack.org/oslo-config/oslo-config-2013.1b3.tar.gz#egg=oslo-config

and it worked.

In general - I strongly recommend ALWAYS using pip install over
easy_install. But that doesn't seem to be the real key here.

Back to the drawing board...
