Hello,

I'm trying to install devstack (grizzly) on Ubunutu 13.04 it fails in nova installation:

pip.log looks likes:

Exception information:

    status = self.run(options, args)

This problems seems very consistent. I tried out on Ubuntu 12.04 and I get the same. Also my localrc is pretty straightforward:

#Pin the version

GLANCE_BRANCH=stable/grizzly

Many thanks for any help!
