Breaks due to some Pip issues

I've been using this role for a while, but recently have it making my builds fail trying to install docker-compose. I get this:

Successfully built docker-compose docopt PyYAML texttable dockerpty enum34 functools32
Installing collected packages: docopt, PyYAML, requests, texttable, six, backports.ssl-match-hostname, websocket-client, docker-py, dockerpty, functools32, jsonschema, enum34, docker-compose
  Found existing installation: PyYAML 3.10

Detected a distutils installed project ('PyYAML') which we cannot uninstall. The metadata provided by distutils does not contain a list of files which have been installed, so pip does not know which files to uninstall.

Nothing in my scripts changed. Seems like this is an issue with new docker-compose installation (which I'm not sure is even needed for this role in the first place).

Seems this is actually only an issue with pip 8.0.0 installing docker-compose. Closing here. If you have the same issue as me, just downgrade pip.
