Mike, your PGM file has a couple of problems.  First, xv thinks it's
truncated (and pgmtoppm spins forever trying to read it, which backs up
xv's assertion.)  Second, the lines are too long: the pgm spec says lines
must be 70 characters or less.  I don't know if either of these is what
causes POV to choke on the file, but none of my other tools want to work
with it either.
