The setup.py script tries to import future and if it fails it then attempts to pip install that library [0] that seems to be a hack and needs to be removed because it causes a lot of pain on system that is trying to package the library. For example, when packing for RDO this problems appears:

Another problem this would raise is that, in order to execute anything in setup.py (say just do python setup.py sdist) will require a privileged user otherwise we won't have permission to install the library via pip, for example:
$ python setup.py sdist

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Thanks for submitting this bug.
Yes I did that and that's a dirty hack. :)
I'll try to fix it ASAP.
