This looks as though you are running the latest python from python.org, not the pre-installed python from Apple (that's good).

I DON'T know how tk is getting mixed into this, it shouldn't be.  But I think I can tell you how to get matplotlib working...

Matplotlib DOES do 64-bit, the problem is numpy, which as you download in binary form does not.  But, if you copy the bash script here:

	https://raw.github.com/fonnesbeck/ScipySuperpack/master/install_superpack.sh

it will download the sources and build a 64-bit numpy, which will then give you a default 64-bit full package of python, numpy, and matplotlib.

That's what I've done, and my system runs the demo you listed in your post with no problems.
