That error is the same one I get if I try to build from source like the
wiki says using the old ./configure, make, sudo make install. I can do an
install fine with the AUR package, mythtv-git, but I have to modify the
PKGBUILD file to use v35 and eliminate the python-future dependency.
However, I can't remember the last time I did that successfully if I test
find_orphans.py.

I'm betting it's a dependency issue, but having to depend on AUR
maintainers for weird Python packages is suspect at best.  In my NUCBOX,
it's easy to switch out the NVME drive and test something else.  So I've
pulled the Arch SSD and put it in timeout so it can think about how it
screwed up.  In the meantime I'll test something on Debian that I wanted to
do for comparison.

I did find something about pip and AUR. I can't say I understand all of it:

All python PKGBUILDs are built with --without-ensurepip, and pip is
provided via the python-pip package, which is built for the system-wide
python environment as a "site-packages" package. If you build any other
python version from the AUR, then you're supposed to use virtual
environments for any of those other python versions. In those virtual
environments, pip gets installed separately, and this is where you can also
upgrade or even remove it.

$ yay -S python311
$ python -m virtualenv -p /usr/bin/python3.11 /path/to/venv
$ source /path/to/venv/bin/activate
$ python --version
$ python -m pip --version
