Starling, Nape, Flash, Haxe Dillemma

Question

I am building a game in Flash for iOS using the Starling Framework. I am also using Nape, a 2D Physics engine. The problem I am experiencing is a particular method on the Nape engine uses flash.display.DisplayObject, however, because I am using the Starling framework, I instead have to use starling.display.DisplayObject. It returns this error:

1067: Implicit coercion of a value of type flash.display:DisplayObject to an unrelated type starling.display:DisplayObject.

There is no way to adjust this method. The Nape engine is compiled into a .swc, which I am unable to edit. The engine is also open source, but it is done in Haxe, and I cannot figure out how to compile it once I have edited it.

The source can be downloaded here: http://deltaluca.me.uk/docnew/

I need to change all the flash.display.DisplayObject in the nape.utils.Debug class to starling.display.DisplayObject.

If you can lend me any advice I'd be really greatful.

Here is what I do, pretty simple. Let me know if you have any more questions.

When creating the Space -typically when the scene is created:

/**
 * Create debug drawing space to overlay on assets if flag enabled in Release config
 */
if(Release.DEBUG_PHYSICS){
    _debug = new ShapeDebug(320*2, 480*2, 0x000000);
    _debug.drawConstraints = true;
    _debug.drawCollisionArbiters = true;
    var MovieClipDebug:MovieClip = new MovieClip();
    MovieClipDebug.addChild(_debug.display);
    Starling.current.nativeOverlay.addChild(MovieClipDebug);
}

When the stage is destroyed:

if(Release.DEBUG_PHYSICS){
    _debug.clear();
    _debug = null;
}

When the graphical engine updates:

/**
 * Update the positions of the depug layer
 */
if(Release.DEBUG_PHYSICS){
    _debug.clear();
    _debug.draw(_space);
    _debug.flush();
    _debug.display.x = this.x;
    _debug.display.y = this.y;
    // handles camera zooming in/out
    _debug.display.scaleX = this.scaleX;
    _debug.display.scaleY = this.scaleY;
}
