Storing debug log for failure in /home/user/.pip/pip.log

Setup details: Ubuntu 14.04 and yes I did have previously install requests (2.12.3) also tested in virtualenv (can provide the full pip freeze on request)

Managed however to install from source by changing in the requirements.txt the line requests ~=2.11 to requests >= 2.11.
