Also note though, if it can be uninstalled, we have often had problems
with the packages coming back and overwriting the pip installed
version, which leads to often very obscure problems.  For this reason
in various bits of devstack/devstack-gate/dib's pip install etc we
often install and pin packages to let pip overwrite them.
