Switching on debug for pstoimg reveals the error message to be misleading
:
{{{

pnmcolormap: Image already has few enough colors (<=256). Keeping same
colors.

RGBDEF to the pathname of your rgb.txt file or don't use color names.

Searching for '''rgb.txt'''
{{{

Trying again, following the hint from the debug ... succeeds to create the
pngs :
{{{
export RGBDEF=/opt/local/share/netpbm/rgb.txt
latex2html to.tex
...
}}}
The installation would be improved if it was not necessary to set this in
the environment.
