The problem was that mod_wsgi was compiled for Python 2.7 and it needed to be recompiled for Python 3.3. I did not find a new mod_wsgi available anywhere as a package so I recompiled it.
Since Python 3 is an alternate install on CentOS 6.4 .configure had a difficult time producing a good Makefile, even passing the --with-python option. I needed to edit Makefile a bit after getting the information from python3.3-config --cflags and also with --ldflags options.
HTH someone in the future.
