Hi Michael,

I'm in my lab machine today and it has Rocky8.7 with Python 3.6.8. The output is below. Looks like I need to upgrade python in this case.

I can follow up soon with Fedora 37 and Python 3.11.

Thanks!

Congratulations on being perhaps the first person to try P4P with python 3.11!

I haven't yet published pre-compiled .whl files for python 3.11, so I guess
something went wrong during local compilation.  Could you try the following
with a new virtualenv?

> . anotherenv/bin/activate

> python -m nose2 p4p

This adds a '-v' which will print quite a bit of detail while building p4p
and its dependencies.  Please send me the full output.
