You should consider upgrading to 4.1beta.  This version has which
allows you to define a legend for a map.  Here are some tricks that I
discovered while trying to put out a black-and-white patterned ps file with
a legend.

For those interested...

I have been using in grass4.1beta to create a ppm file containing a
map with a legend.  Hardcopy is to be produced on a black-and-white PostScript
printer.  I was having problems rescaling the map to fit on  8 1/2 x 11 inch
paper and, when I finally solved this problem with help from this list, my
rescaled map did not include the bottom frame line.  So, here are the tricks...

Last summer I recall a hack posted by Raymond Venneker to restore the bottom
frame line (don't know why this wasn't included in 4.1, but it wasn't):

1)  edit  .../src.alpha/paint/Programs/ as follows:


        Ppictsize (fullwindow.rows+extra_lines, pixels+MARGIN); 
        Ppictsize (fullwindow.rows+extra_lines+MARGIN, pixels+MARGIN);  

    then recompile.

2)  To produce the PostScript map on a B&W PS printer (e.g., an Apple
    LaserWriter), rescaled to fit on 8 1/2 x 11 inch paper, issue the following:

      ppmtopgm 'yourfile.ppm' | pgmtops -s 0.5 | lpr -Pps10

    Of course, you will substitute the appropriate ppm file name and printer
    name for your installation.

Thanks to all of you who offerred help in unraveling this mystery!
