In my case, the problem was that I had uninstalled NumPy (from kyngchaos
GDAL).  It was causing a conflict with Macports scipy stuff.  The macports
version is installed as "universal" but apparently is actually just 64
bit!  
So the workaround I have at the moment is to install NumPy when I need to
use GRASS 7, and then uninstall so I can use macports python (which I need
for other libraries and such).
This seems like a inconvenient fix for now.  Is there any way to set some
paths so that they can both co-exist and GRASS will find the correct one?
