A useful tool that anvil has built into it (thanks to aababilov). It might
be useful in this situation.
It might be useful to use said tool (or a derivative) to detect this kind
of version conflict earlier rather than later??
It is used in anvil to determine the same set of conflicts so that later
when multiple single packages of openstack (say of a given release) that
said multiple packages will all play nicely together (at least with
respect to pip requirement versioning).
