In addition to the symptom you're reporting, you have a precedence problem that you haven't spotted yet. 
  open FILE, ">testfile.log" || 
        die "Unable to create file: $!";

isn't the same as 
  open(FILE, ">testfile.log") || 
        die "Unable to create file: $!";

or 
  open FILE, ">testfile.log"
        or die "Unable to create file: $!";

In the first case, you will never, ever see that die. In the second and third cases, you will. Consult the Perl operator precedence table in perlop for details.

Further, you can save yourself a lot of confusion by using the three argument form of open. E.g., 

  open(FILE, ">", $log) or die "$log: $!";

This allows you to pass around filenames in variables without polluting them with extraneous symbols.
