newbie help wanted with installing/using netpbm through macports

[Ryan Schmidt]

I see now that ppmtomd is more difficult to compile than most  
software. As such, as soon as someone figures out how to do it, a  
portfile should be created so nobody else has to figure it out again.

I'm working on a portfile. I'll see how far I can get.
