I'm making a call to an external program (gnuplot) using the backtick method. As in: 
my $output = `gnuplot $cmd`;

[download]
The problem is that gnuplot isn't doing what I expect (it's supposed to create a file) and $output is empty. This is running inside a cgi so the user is apache and I suspect some sort of permissions or path problem. I am looking for some sort of message like "command not found" from the system. There might also be buffered stdout from gnuplot telling me of a problem but I'm not getting it. Is there something more I need to do to get those messages?

Thanks,
Bret
