newbie help wanted with installing/using netpbm through macports

[Ryan Schmidt]

I just added the ppmtomd portfile. Wait 12 hours, then "sudo port  
selfupdate", then "sudo port install ppmtomd".

If you're interested to see what I had to do to get it to work, you  
can "port cat ppmtomd" and "cat `port dir ppmtomd`/files/patch- 
Makefile.diff".
