How do I debug actionscript in ming?

This c code is inspired from the perl example in Shawn Wallace's perl graphics
programming book.
Feel free to give constructive criticisms on all bad form.  
I know there's lots by the way since this was a quick try.

It's the astral tresspassers sample but it isn't quite perfect.  
I am trying to fix:
-Game Over text to get displayed
-mouse moving the gun
-mouse clicking launches a bullet

In other words I have a feeling the _setName isn't successful or getting set for
the wrong level/kind of object.

The only real problem I have is I would like to debug the actionscript with ming
on a linux box but it's not evident.

The ming astral.swf gets generated with success.  The debugging I would like to
do is from within the web browser.  Is there such beast as debugoutput commands
done from within actionscript that get redirected to a browser java console
somehow?

Thanks for any tips.

Cheers,
David Marceau
