I make it a point to never use a python build that comes from a .deb for any real development.
The OS vender may require certain python features for its management scripts, but I don't like my development tools changing out from under me. Build yourself a python from source, putting it some where in, say, /opt then modify your PATH in .bashrc to find yours first (or only). Then always develop in in virtualenv (based on your python) and no dist-packages directories about it. If you need to install something in python, use pip, never apt-get (though you may need apt to install C library dependencies.
