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
 Organization:  USGS-NMD  DLG DATA - CHARACTE
 Map Name:      SAN FRANCISCO, CA
 Source Date:   1978,
 Orig. Scale:   100000
 North: 38N
 South: 37:45N
 East:  122:45W
 West:  123W
Plotting ... Done
But I see nothing at all in the X display. Any ideas..
