Maybe some part of the code you use (like a library to the connect to 
the backend) has debugging print statements in it?

You could try to run that code in isolation from the command line (that 
is, not through the browser and web server) and see if it produces output.

And/or you can try a trick like described in here:
http://stackoverflow.com/a/3508679/14132
to capture output, but only from within Perl (if it calls a C library 
that prints to STDOUT, this won't capture it).

Hope this helps,
Moritz
