P5 should be fine (that's just "greyscale").

What happens if you run the commands specified in wwwgui.cf by hand, one
after each other, on the files (from the command line)?  That is:

$g3topbm <file.g3 >outfile1.pbm
$pnmscale -xscale 0.1 -yscale 0.1 <outfile1.pbm >outfile2.pgm
$ppmquant <outfile2.pgm >outfile3.pgm
$ppmtogif <outfile3.pgm >outfile4.gif

I assume that it's failing in the ppmquant step - which program did you
use for that?
