okay on the system (Archlinux VM) where I built using the makepkg -si. On
the AUR PKGBUILD method I see:

/home/jim/mythtv-git/pkg/mythtv-git/usr/lib/python3.13/site-packages/MythTV/services_api/_version.py
/home/jim/mythtv-git/src/mythtv/mythtv/bindings/python/MythTV/services_api/_version.py
/home/jim/mythtv-git/src/mythtv/mythtv/bindings/python/build/lib/MythTV/services_api/_version.py
/usr/lib/python3.13/site-packages/MythTV/services_api/_version.py
