Can't run tests in liberty cloudarchive environment

[Sam Morrison]

Trying to run tox for my liberty branch inside a ubuntu liberty environment and get the following error: (pip version is too old I think)

Status changed to 'Confirmed' because the bug affects multiple users.

Had the same problem trying to run the neutron test suite on Ubuntu 15.10. A new pip version fixed it for me.

Ubuntu ships with pip 1.5.6. But according to the pip docs, you need at least version 6 to parse one of the openstack requirements.txt
