It appears that I am running 32 bit python. But my computer is a MacMini
with an Intel Core 2 Duo, which is supposed to be 64 bit. The python
distribution I have installed is Enthought. When I install enthought,
everything works smoothly and installs fine, but I would like to be able to
update to the current svn trunk to test out the newest features.
