Thank you for the explanation.  It turns out I did find a work-around whi=
ch is exactly what you mentioned.  The only difference is instead of spec=
ifying the file name twice, I was able to get it only once and use the 'f=
ile' option to :results:

#+BEGIN_SRC perl :results output file :exports results :var fname=3Dimage=
.png
  use GD;
  my $image =3D build_pic();
  open( F, ">$fname" );
  binmode F
  print F $image;
  close( F );
  print $fname;
#+END_SRC

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 s=
pecify the filename once, and Org will still create a link for the result=
s section:

#+RESULTS:
[[file:image.png]]

Thanks again for your help and info!
