Error when installing pbr

I want to install openstack client on my machine running OSX 10.8.5. As a prerequisite, i need to install pbr. So, i did the following

git clone git://github.com/openstack-dev/pbr.git
cd pbr
sudo python setup.py install

But im getting the following error trace

This is because the build from the git repo is in development, and might have bugs. I used pip to install pbr from the stable release version (on pypi) like this:

sudo easy_install pip # if you don't already have pip
pip install pbr

If you have easy_install or pip then follow this tutorial.

If you don't want to use a package manager like easy_install or pip. Then you can head over to the PyPI page, and download the tarball. Simply extract the tarball and run python setup.py within the pbr package. But install pip will save you a lot of hassle in the future.
