Installation of requirements.txt with pip fails on sphinxcontrib-fulltoc

[LeShadow]

When I try to install elasticHQ, when i'm on the step of using pip to install all requirements, I get the following error:

Collecting sphinxcontrib-fulltoc==1.2.0 (from -r requirements.txt (line 40))

Can you try:

pip install --upgrade pip setuptools

I think I will separate the docs generation requirements from the app, to avoid this in the future.
