Fix for Python library path problem

You seem to be the odd person out.  We now have confirmation of my rule
(/usr/lib/X/Y in sys.path implies /usr/local/lib/X/Y in sys.path) from
Gentoo and two versions of CentOS, as well as my Ubuntu 16 and
Raspbian systems.

>>> import distutils.sysconfig
>>> distutils.sysconfig.get_python_lib()
'/usr/lib/python2.7/dist-packages'
