Thanks much for your response!  I gave it a try, but the message just
changes to "Graph_Set:  Can't open :0.0".  I'm wondering if there is some
kind of permission problem.  But I have been running GRASS as root to
minimize that.  My understanding of what to check the permissions of is
rather limited, unfortunately... Regards, Tom
