	I just did a few tests and setting the filename to "-" is sending
the output to STDOUT. Does the code below produce a valid file if you
specify a real filename instead? Can you get it to work if it isn't
running under mod_perl? For comparison I'm running RRD 1.0.7 (yeah I know
I should upgrade) with Perl 5.005_02 on Linux.
