Problem with Mac::AppleScript and PAR

[H. Wade Minter]

I've got a fairly complex Perl/Tk application that I'm rebuilding with  
PAR on a Mac for the first time in ages.  I'm having a problem with  
Mac::AppleScript that I can't figure out.

Here is the relevant section of the code:
        elsif ( $^O eq "darwin" )
        {
            return
              if (
                RunAppleScript(
                    qq(tell application "System Events" to (creator  
type of processes) contains "Audn")
                ) eq "true"
              );
            print "Starting AppleScript\n" if $debug;
            RunAppleScript(qq( tell application "Audion 3"\nactivate 
\nend tell))
              or infobox(
                $mw,
                "Audion Error",
                "AppleScript could not find Audion.  You will  
probably want to download the app and put it in the Applications  
folder.  Otherwise you will not be able to, in a word, 'play' any  
music.  $@"
              );
            print "Finished AppleScript\n" if $debug;
        }

If I run the script straight from the command line, it works fine.   
However, if I do a "pp -o mrvoice mrvoice.pl" and then run the  
resulting "mrvoice" file, it bombs out with an AppleScript error  
"-1753", which appears to be a "Script Error".

Any ideas what might be causing this AppleScript problem when running  
under PAR?

Thanks,
Wade
