Make sure PVW python3 dependencies are installed to correct location
!583 (merged) Introduced a workaround to #119 for python2, but the real fix would have been to make sure that all the python modules got installed to <INSTALL_DIR>/lib/pythonX.Y/site-packages
rather than <INSTALL_DIR>/local/lib/pythonX.Y/dist-packages
.
When we move to Python3, we should make sure this gets fixed properly.
