Well, whatever Python is detected (python3 has preference over python2),
needs to have the -devel package available too. Detection is done by
probing the python<X> executable. The Matching header files from -devel
need to be present in order to be able to build glupy (and others?).

I do not think compatibility for python3/2 is the problem while
building the tarball. The backport might become relevant while running
tests on environments where there is no python2.
