I found another port which I think can be updated fairly easily. The  
netpbm graphics routines are required for FuzzyOcr. One of the tools  
FuzzyOcr uses is called pamthreshold and it is only available in  
netpbm 10.34 or later. I edited the portfile to use 10.34 as the  
version, and updated the md5 hash for the 10.34 .tgz archive and  
installed the port. It installed normally, and I tested the several  
of the utilities required for FuzzyOcr including pamthreshold, and  
they seem to work fine.

This may be useful for others who are wanting to get rid of those  
annoying image spams.
