A couple of questions Royce,

1. Both GRASS 6 and 7 require frameworks (dependencies). As of Friday, the dev 
versions (including GRASS 7) require several newer versions of the frameworks 
than does the stable version of GRASS (6.4.3). Did you download all required 
framework versions?

2. Have you installed a 3rd party python (e.g., Macpython) or a separate 
install of wxPython? 

3. What version of the Mac OS are you running?
