Have you tried: eselect python cleanup emerge --depclean -v -p emerge @preserved-rebuild -v -a I don't have any python targets specified and on a (mostly) stable system I get: $ /usr/bin/python --version Python 3.8.7 $ eselect python list Available Python interpreters, in order of preference: [1] python3.8 [2] python3.9 (fallback) $ ls -al /usr/bin/python lrwxrwxrwx 1 root root 13 Feb 13 09:04 /usr/bin/python -> python-exec2c $ emerge -1Dvp pyyaml These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild N ] dev-python/pyyaml-5.4.1::gentoo USE="libyaml -examples - test" PYTHON_TARGETS="python3_8 (-pypy3) -python3_7 -python3_9" 170 KiB Total: 1 package (1 new), Size of downloads: 170 KiB It would use PYTHON_TARGETS="python3_8" which is the default on this system, since I have not modified my python settings.
