Mac OS X - Deployment

[Matt]

Hi Everybody,

I just spent about an hour googling and still can't find out how to deploy a 
Python app to Mac OS X.

I just finished a simple Hello-World GUI app using wxPython and deployed it to 
a WinXP system using PyInstaller. So I am familiar with the basic tools.

It would be great if I could build an OS X executable from my XP system. Is 
that possible? If so, is it documented anywhere? 

If I can't do it on XP, I suppose I would have to install Python and wxPython 
on a Mac, then copy over my HelloWorld.py file, but what then? I know how to 
make DMG files, but what woudl go into the DMG?

I am used to REALbasic where you write your code and then push the "Build" 
button and executables for Linux, Windows, and Mac are created in less than a 
minute. Maybe the Python world will be as advanced one day...

Thanks,
Matt
