Thanks Scott. I appreciate your desire to get the solution

In my case I just reconfigured and re-installed gdal-1.3.1 with:

./configure
	--mandir=/usr/local/share/man
	--without-python
	--with-threads
	--with-static-proj4=/usr/local
	--with-libtiff=/usr/local
	--with-geotiff=/usr/local
	--with-jpeg=/usr/local
	--with-gif=/usr/local
	--with-png=/usr/local
	--with-jasper=/usr/local
	--with-pg=/usr/local/pgsql/bin/pg_config
	--with-mysql=/usr/local/mysql/bin/mysql_config
	--with-netcdf=/Volumes/disk1/home1/kwythers/src/netcdf-3.6.0-p1
	--with-hdf4=/Volumes/disk1/home1/kwythers/src/HDF4.2r1/hdf4-darwin
	--with-ogdi=/usr/local
	--with-geos=/usr/local/bin/geos-config
	--with-grass=/usr/local/grass-6.1.cvs

Perhaps this approach would be more efficient. I assume that http:// 
www.gdal.org/dl/gdal-grass-1.3.1.1.tar.gz  does not rebuild and  
reinstall whole gdal application?

I agree your approach would be simpler. Although since have not had  
any trouble getting qgis builds to read grass vectors or rasters, it  
would seem that both approaches work.
