Where do I get a ppm driver?

I would like to save a GRASS raster map as a ppm. The following should
work:

p.select ppm
p.map.new input=map_script

...but I don't have a ppm driver in /path_to_grass/etc/paint/driver. I just
have "preview" and "preview2". I am running GRASS 4.2.1 on Red Hat Linux
5.2. I did not compile GRASS myself, I just downloaded the binaries. Just
to make sure I am on the right path, I did the following:

p.select preview
p.map.new input=map_script

...after writing a file called map_script, of course. It worked, so I am
sure that my only problem is finding a ppm driver. If anyone can point me
in the right direction, I would be very grateful.

You can also use the CELL driver (redirect d.mon in a Grass raster
file),
then export the grass raster file in tiff (or something else), then
use xv (or imagemagik, or pbmplus) to convert your tiff file in ppm.
Not a direct way, but that may be batched too.
