[gentoo-dev] PYTHON flags grammar? why?

Out of sheer curiousity, why does make.conf need all 3 of... PYTHON_SINGLE_TARGET=python2_7 Because some packages only accept a single version of Python. e.g. Blender, systemd. I think this also applies to the default Python version for packages that install executables. PYTHON_TARGETS=python2_7 Because the Python ABI [*] requires different libraries to be built for different versions and installed in different places. /usr/lib/python?.? [*] not really a binary interface, but let's call it that USE_PYTHON=2.7 This is deprecated, AFAIK and used for old packages that do not support PYTHON_TARGETS.
