It probably means you're installing with an old pip. The most common
way that happens is using distribution versions of virtualenv, because
of how pip gets installed in tox virtualenvs:

virtualenv makes the environment
virtualenv takes a cached wheel from the environment *that virtualenv
ran from* and unpacks it into the tox environment.

tl;dr: sudo apt-get remove python-pip python-virtualenv; install pip
using get-pip.py; sudo -H pip install virtualenv
