Quite honestly, if we demand that buildfarm owners install some
version of python that their platform doesn't package, they will
simply not enable pytest testing.  Care and feeding of a BF
animal is already a nontrivial investment of effort.  I'm especially
not believing that people will install two different python versions
in support of this.
