bundlebuilder sets no such magic attribute to my knowledge.

 From PyObjC you can tell by looking at NSBundle.mainBundle().  
Depending on how the bundle is built, you might be able to tell by 
looking at sys.executable or sys.prefix.  Not sure.

py2app, when it's done, will behave more like py2exe in this regard.
