Failing installation with pip

[rodrigogadea]

Installing mezzanine-blocks with pip as suggested in docs is failing:

> pip install git+git://github.com/renyi/mezzanine-blocks.git
Collecting git+git://github.com/renyi/mezzanine-blocks.git
  Cloning git://github.com/renyi/mezzanine-blocks.git to ./pip-_uDggH-build
Requirement already satisfied (use --upgrade to upgrade): pip in /home/rodrigo/.virtualenvs/dartel/lib/python2.7/site-packages
Collecting install
  Could not find a version that satisfies the requirement install (from versions: )
No matching distribution found for install

I also had this issue, it looks like pip is not up to date with the latest version.

Changing my requirements.txt file from mezzanine-blocks==0.9.4 to git+git://github.com/renyi/mezzanine-blocks fixed this issue.
