I wanted to bring my comment I made elsewhere on my Mac testing into this, more appropriate thread: I just tested one of the available modules on a local DEM file, and here is there error message that appeared when I ran it: Cannot start module r.slope.aspect command: /usr/local/Cellar/grass/6.4.2/grass-6.4.2/bin/r.slope.aspect --interface-description ERROR: GISRC - variable not set Note that I am running a version of grass installed locally, not from the application that William makes available.
