I suggest that you first try the version from the GRASS website:


If you have problems with the OpenOSX versions, you would be better
off asking OpenOSX. AFAIK, none of the GRASS developers are
particularly familiar with the OpenOSX version.

I suspect that the problem is that the OpenOSX version is out of date. 
Apple's X11 support is something of a moving target. IIRC, prior to
Leopard, it was necessary to explicitly start X11, but that isn't
necessary (and doesn't work) in Leopard.
