Created attachment 546880 [details] emerge --info When trying to get the sitedir with `python_get_sitedir`, the python2.7 variant yields "//usr/lib64/python2.7/site-packages" instead of "/usr/lib64/python2.7/site-packages" The underlying code fragment that is executed is this: /usr/bin/python2.7 -c 'import distutils.sysconfig; print(distutils.sysconfig.get_python_lib())' (Taken and expanded from https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/python-utils-r1.eclass#n398) If I execute this in a terminal, it yields the correct result (without double-slash). Yet, if I execute the following //usr/bin/python2.7 -c 'import distutils.sysconfig; print(distutils.sysconfig.get_python_lib())' It yields the erroneous output with the double-slash. If I execute the same line with any other python interpreter, I _always_ get the correct result. As a quick-fix I added a line that strips out any double-slashes after https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/python-utils-r1.eclass#n398 PYTHON_SITEDIR="${PYTHON_SITEDIR/\/\//</}" I am running a ~amd64 system, so I have * sys-apps/portage-2.3.49 * dev-lang/python-2.7.15

That output would seem to indicate that the eclass is calling //usr/bin/python2.7. The only way I can see that happening is if EPREFIX is set to "/" (it should be empty), or you are overriding the PYTHON variable somewhere.
Ah. EPREFIX was not set anywhere, but it reminded me of a patch I wrote against distutils from a few years back, that allows cross-compilation of python packages to different architectures. With that patch reversed the problem vanishes. Interestingly, cmake never had hiccups before due to an extra slash, only recently did this start to break the builds...
