Thanks Philip and Michael, for your help. It was useful, but I am
afraid I am not quite there yet.
v.import, which I used, WAS setting the latitude and longitude
region parameters incorrectly. I used v.digit to correct that.
Then I ran g.region to set the region from the vector map. Let me show
you the output from two commands. "sf.rds" is the name of the map that
I am trying to get running.
GRASS 4.1 > g.region -up
projection: 3 (Latitude-Longitude)
zone: 0
north: 38N
south: 37:45N
east: 122:45W
west: 123W
nsres: 0:00:06.47482
ewres: 0:00:06.47482
rows: 139
cols: 139
Mapset <PERMANENT> in Location <sanfran>
GRASS 4.1 > g.region -up vect=sf.rds
projection: 3 (Latitude-Longitude)
zone: 0
north: 38N
south: 37:45N
east: 122:45W
west: 123W
nsres: 0:00:06.47482
ewres: 0:00:06.47482
rows: 139
cols: 139
The above would indicate that the default region is now the
same as the map region(?)
Then I ran the d.vect command on my imported map.
Mapset <PERMANENT> in Location <sanfran>
GRASS 4.1 > d.vect sf.rds
Vector file [sf.rds]
Selected information from dig header

Plotting ... Done
But I see nothing at all in the X display. Any ideas..
