ppmquant is a perl script which calls another script "pnmquant" 
without "/sw/bin/". Please check:

1) Is the "pnmquant" in the directory /sw/bin ? If it does not 
exist, please check the installation of Netpbm. 

2) If it exists in the directory, please check your PATH 
environment variable to include the directory "/sw/bin":

 $ echo $PATH
