If you throw in a line at the top that says something like

	$ENV{'PATH'} = '/bin:/usr/bin:/etc:/usr/etc:/usr/ucb';

(or whatever) I bet it would work better.  cron doesn't keep much of a PATH.
Another place people get in trouble is running programs that want a
controlling terminal, though I don't think that's your problem.
