I spent some time looking into this.  The problem is that upstream 
includes binary eggs (which are Python version specific) as part of its 
test suite.  The problem here is that there are no eggs included for 
Python 3.10.  Upstream is aware of this[1] but unfortunately, that patch 
can't be applied because it is a binary patch.  They have also later[2] 
removed the binary eggs completely, but that patch can't be applied either 
because it involves files that are not in the PyPI distribution.  The best 
solution might be do what Fedora did[3], but for that we'd probably have 
to switch to using a GitHub tarball instead of the PyPI tarball because 
the PyPI tarball is missing files.
