Investigating further.  I think there has been some change to effecting where PIP
places files which breaks an assumption I am making.  (a lib/ vs. lib64/ thing)
I'm not yet certain if this is a question of redhat vs. debian difference, or of
pip version.

Matt, please try updating the pvxslibs module.  Then re-test.

pip install -U pvxslibs==1.1.2a1

Building P4P as an epics module still works.

Cheers,

            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?

             > python -m virtualenv anotherenv
             > . anotherenv/bin/activate
             > python -m pip install -U pip
             > python -m pip install nose2
             > python -m pip install -v p4p
             > 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.
