PYTHON_TARGET determines for which version(s) of Python a package
installs its modules. The modules may be identical, but 3.7 and 3.8 have
different search paths, e.g. /usr/lib/python3.7/site-packages vs.
/usr/lib/python3.8/site-packages.

It is possible you have some old python_targets settings in package.use,
that's where I would check first.
