This could be a memory problem, so check the CGI's own memory 
partition in Get Info, but in my experience using Mac web sharing as 
a test setup for CGIs that I deploy elsewhere, that error -- 
"document contains no data" -- comes from the web server when the CGI 
returns an error or warning instead of proper http output. You might 
want to run the same script directly, not as a CGI, and check your 
MacPerl output for warnings from the -w flag or from "use strict".

You might get output that looks fine, but at the very end there will 
be some error/warning messages. Work on your script until those don't 
appear any more, and then convert to CGI.

Or, take the time to add to your script something like what CGI.pm 
provides for reporting out errors as http responses, making use of
   use CGI::Carp 'fatalsToBrowser';
