Maybe I missed it (or maybe there are disadvantages I am not aware of), 
but I think I did not see the suggestion to simply use the hdiutil 
command. The snippet below is part of the Makefile for building a Task 
Coach release. The make.py is a distutil script that creates 
TaskCoach.app. hdiutil then packages the app as a dmg:

macdist: icons i18n
         $(PYTHON) make.py py2app
         hdiutil create -ov -imagekey zlib-level=9 -srcfolder 
build/TaskCoach.app dist/TaskCoach.dmg
