The ``Build Applet'' tool that is placed in the MacPython 2.5 folder is fine for packaging small Python scripts on your own machine to run as a standard Mac application. This tool, however, is not robust enough to distribute Python applications to other users.
The standard tool for deploying standalone Python applications on the Mac is py2app. More information on installing and using py2app can be found at http://undefined.org/python/#py2app.
