This may not be what you're looking for, but when I'm testing a script, I redirect STDERR to print to STDOUT. That way I can pepper my script with print statements to see what is going on so that I can debug it. This is how I do it:

BEGIN {
  $| = 1;
  open(STDERR, ">&STDOUT");
  print "Content-type: text/html\n\n";
}

Hope that assists you.
