[gentoo-dev] [PATCH 12/12] distutils-r1.eclass: Add a safety check for wheel install done

[Michał Górny]

Add a safety check to verify that distutils_wheel_install is being
(usually indirectly) called in python_compile(), when using PEP517
build.  If it weren't, this usually indicates that
distutils-r1_python_compile (or distutils_pep517_install) was not
called.
