Thanks, but we can check Python version from Python scripts themselves,
before importing the problematic modules:

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 is
Mac 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.
