[gentoo-dev] [PATCH python-utils-r1 3/4] Ban calling pythonY and pythonY-config when pythonX is used

[Michał Górny]

Ban calling python3{,-config} when python2 is used, and the other way
around. While this will not prevent configure scripts from finding the
other Python version, it will cause them to fail eventually trying to
use it. Currently those attempt were able to pass through thanks to
python-config providing python{2,3} symlinks.
