Gary - yeah, I've been lurking on this thread...

Ah, the GDAL framework has it's own minimal set of GRASS libraries to  
support GRASS formats without having it installed.  These are the  
stable 6.2 GRASS libraries.

When running GRASS, then running Qgis from GRASS, GRASS has set up  
DYLD_LIBRARY_PATH to point to its libraries.

What are the Qgis grass plugin/provider linked to?  Try otool -L on  
them.  They may be picking up the GDAL GRASS libraries instead of the  
GRASS.app libraries.


That's what I can think of for now without trying it myself.  I've  
been hesitating to plunge into the cmake switch with Qgis, so I don't  
know if I'll be able to look at it myself any time soon.
