You are right with the issue. `python3_8` in `PYTHON_TARGETS` causes the
problem. However, I don't understand the reason for it.
In /usr/portage/profiles/arch/amd64/use.stable.mask Python 3.7 and
Python 3.8 seems to be deactivated while
/usr/portage/profiles/arch/amd64/use.mask enables only Python 3.8 again?
However, in conclusion this seems to result in a mask for
python_targets_python3_8. But this settings seems to be respected only
by setuptools. This seems to be also the reason for my initial emerge
error. emerge sees, that meson wants python3_8 but this useflag is
masked in setuptools-42.0.2 so it tries to update it to 45.2.0.
When I remove "python3_8" from my make.conf, I get this output:
```
emerge -a1 "=meson-0.52.1::gentoo" "=setuptools-42.0.2::gentoo" -v
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] dev-python/setuptools-42.0.2::gentoo USE="-test"
PYTHON_TARGETS="python2_7 python3_6 python3_7 (-pypy3) (-python3_8)" 0 KiB
[ebuild R ] dev-util/meson-0.52.1::gentoo USE="-test"
PYTHON_TARGETS="python3_6 python3_7 -python3_8" 0 KiB
```
Why is python3_8 profile masked in setuptools by not in meson?
Thanks,
