Updating py-setuptools

[John Klos <john%ziaspace.com@localhost>]

Hi,

Unfortunately, due to still running mailman, I still have to have python 
2.7 around. This leads to not being able to use pkg_rolling-replace for 
updating python related things, but that's OK.

Updating devel/py-setuptools works fine for python 3.8, but when trying to 
updated for 2.7 it keeps trying to rebuild fully-up-to-date python 2.7:

make PYPACKAGE=python27 PYTHON_VERSION_DEFAULT=27 package update
...
=> Full dependency python27>=3.8: NOT found
=> Verifying update for ../../lang/python27

Now I see that there's a separate version of setuptools for python 2.7 
(devel/py-setuptools44) and I see that updating there works, but:

1) shouldn't a package that's explicitly told to use a version of python 
fail if the package doesn't support that version?

2) py-setuptools44 fails without PYTHON_VERSION_DEFAULT=27 set in addition 
to PYPACKAGE. Shouldn't one imply the other?

Thanks,
John
