Michael, you have to install it
http://netpbm.sourceforge.net/doc/index.html

Also I found in the pnmscale manual:
pnmscale was obsoleted by pamscale, introduced with Netpbm 10.20  
(January 2004)

I have it on RedHat linux box but I don't have it on Mac or Ubuntu so  
apparently you have to install it yourself.
