Re: [gentoo-user] Q: What is "python-exec2c"? Why would "python3" dispatched through it not see an installed copy of pyyaml?

Check with 'eix dev-python/pyyaml' or 'equery uses dev-python/pyyaml'
for what python versions that module is actually installed for and
compare that with the default python3 version (check 'python3 --version')

You probably need to re-emerge dev-python/pyyaml if PYTHON_TARGETS has
changed. You probably have it installed just for one target (which is
not your current default python3).

$ equery uses dev-python/pyyaml

So I have it installed for python 3.7.x and 3.8.x ...
