Comment 14 for bug 1658844

I believe I figured out the problem. When spinning up a fresh ubuntu 14.04 vagrant machine and manually installing pip with sudo apt-get install python-pip the dependency pkg_resources is installed with python3-pkg-resources to. I experience the same results if I use a ubuntu 14.04 image in an oracle VM. The workaround is to install pip with easy_install via python-setuptools and pip will work.
