With mod_perl, STDOUT does not necessarily go to the browser. It's
better to use the perl "print" function, which at least with the old
mod_perl under apache 1, was overridden by mod_perl to go somewhere
useful (i.e. to the browser).

Can you get RRDs::graph to return the image data in a variable that you
can print, instead of sending it directly to STDOUT?

Cheers, Chris.
