The risk there is that if you do that, you can't modify the scripts to point to python2.4, and will have to change the version of the default "python" binary. I believe you can configure the binary Python installers to do that, but it's a course of action I try to avoid whenever possible.
if sys.hexversion < 0x02040000:error ("Python 2.4 or newer is required.\n\nIf your operating system isMac OS X, please install Python from http://www.python.org/download/mac/.";)
Actually you can do even a tiny bit better than that by following that with a call to
system ("open http://www.python.org/download/mac/";)
which will launch a browser window for the correct location.
