Error using pyrax module on OSX

Question

I'm using the ansible rax.py script for my inventory. The problem I'm experiencing has nothing to do with ansible but with pyrax or pbr.

I've taken the following steps:

sudo pip install pyrax
python
>>> import pyrax

And then I get:

File "/Library/Python/2.7/site-packages/pbr/packaging.py", line 870, in get_version
raise Exception("Versioning for this project requires either an sdist"
Exception: Versioning for this project requires either an sdist tarball, or access to an upstream git repository. Are you sure that git is installed?

According to some github issues one should install pbr separately to get around this issue. I've done this without any luck.

pip show pbr
---
Name: pbr
Version: 0.10.0
Location: /Library/Python/2.7/site-packages
Requires: pip

pip show python-novaclient
---
Name: python-novaclient
Version: 2.19.0
Location: /Library/Python/2.7/site-packages
Requires: requests, iso8601, python-keystoneclient, Babel, oslo.utils, six, simplejson, pbr, PrettyTable, argparse

I'm using python 2.7.5 and not virtualenv. Any help would be greatly appreciated!

Thanks Barry

The following seem to have gotten things into order:

pip install --upgrade distribute

After various version conflicts and all some helpful staff member saved me.
