pnmcat is a standard Netpbm tool (like those used in d.out.file).

Check if you have it: from the grass terminal prompt
  which pnmcat
or just try running it with no options and see if you get a response.


I'd be surprised if it wasn't installed, they're pretty standard & I'm
pretty sure they've been on every Mac system I've looked at.

d.out.gpsdrive also needs netpbm (but doesn't test for it), d.out.file
uses gdal_translate.
