[GRASS-user] Displaying layers - GRASS 6.4.0RC6 with MSYS

I use the Windows-version *GRASS* 6.4.0RC6 with *MSYS* and I want to
display 2 *layers* using following commands for the Spearfish60 sample

d.vect streams col=blue
d.vect roads col=red

The output file map.png only displays the last layer.

How can I display multiple layers with MSYS?

Using the wxGUI interface is not an option, I think, since I want to remake
the example on  http://casoilresource.lawr.ucdavis.edu/drupal/node/340 which
uses a loop (map.png only gives the points of the 5th cluster).

# there are 5 clusters: show them all, and compute convex hulls
for x in `seq 1 5`
do v.extract --o in=bclust where="cluster=$x" out=bclust_$x
v.hull --o in=bclust_$x out=bclust_hull_$x
d.vect bclust_hull_$x type=boundary fcol=none width=2 col=white
d.vect bclust icon=basic/box fcol=black col=black size=6

Any solutions?
