setup.py requires six==1.5.2, citing build problems with newer versions. Pyrax, which is being considered to replace the deprecated py2-only Cloudfiles storage backend, has a dependency which requires a more recent version of six (see #715).

In my test environment, removing the constraint and installing a more recent versions of six appears to work fine. Can we remove the six=1.5.2 requirement?

A user in IRC reported that trying to build against latest git master results in:

IOError: [Errno 2] No such file or directory: 'mediagoblin/_version.py' when making ./bin/python setup.py develop

_version.py was removed in ​https://gitorious.org/mediagoblin/mediagoblin/commit/e6121708e5d1297f92fcecfa4025b222e805c743 to be generated via configure.ac, but this appears to break setup.py (unless someone runs make first?).

Trying to compile a fresh install of latest master results in an error if pybabel isn't installed on the system.
