Indeed, that specific function is the problem and will be removed in the next commit.
I will push a fix as I am already doing some refactoring to the code.
Please note that this code is meant to be part of tempest, it is suppose to have the same base requirements tempest has and since the upstream tempest decided to move from python 2.6 to 2.7, the problem here lies in the choice of running tempest from a machine using python 2.6. (again, tempest requirement[1], not ours.. please note the first two lines :)

There is no real need for the tempest RPM in your case, you can (and probably should as per tempest requirements) simply install tempest on any machine that have python 2.7 (I run it from a fedora 20 machine for example) and it will work just fine.
You do not need tempest running from one of the Openstack instances.
