Added shebang and clean up python3.3.2 installation.

The previous setup_py_3-3-2 had the problem of my lack of under-
standing of virtualenvwrapper. While I needed to install vwrapper
on both system and python3.3.2 installations, I was suppsed to use
the vwrapper shell script from /urs/local/bin/vwrapper.sh and not
the one for python3.3.2.
