To be precise: py2app won't include the base install of Python in the appliction bundle when you use Apple's build of Python. This is make sure that you don't accidently ship parts of the OS in your application bundle (Python is open source, but it is better to be safe than sorry when lawyers can get involved).

What I don't understand is why it tries to load a part of mercurial from the stdlib, this definitely looks like a bug to me.  I wonder how mercurial got installed.
