Err, where did you get this from. In case you are referring to the 
NETPPM toolkit and its CIE/ITU Rec. 709 specification you should be 
aware that this is only valid for files written by this toolkit and not 
for pgm/ppb/pbm/pnm files written by one of the numerous other 
applications in the UNIX world. Therefor pnmgamma (to gamma-correct 
other files) is part of this toolkit.
