Thank you for the explanation.  It turns out I did find a work-around which is 
exactly what you mentioned.  The only difference is instead of specifying the 
file name twice, I was able to get it only once and use the 'file' option to 

#+BEGIN_SRC perl :results output file :exports results :var fname=image.png
  use GD;
  my $image = build_pic();
  open( F, ">$fname" );
  binmode F
  print F $image;
  close( F );
  print $fname;

As you say, this uses Perl to output the file but with the 'file' option to 
":results", Org expects a filename as the output result, I only need specify 
the filename once, and Org will still create a link for the results section:


Thanks again for your help and info!
