Re: [Matplotlib-users] Building current SVN trunk on Mac OS X 10.5

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

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.
