[Pythonmac-SIG] Installer issue - checking for presence of Python 2.2.1?

[Paul Miller]

I've been working on a MindVision installer which contains a copy of the 
2.2.1 vise installer. I would only like to sub-launch the Python installer 
if it is not already installer. I need the technique to work under OS9 and 
OS/X (but I'm only using the Carbon version in both). Searching for 
PythonCoreCarbon 2.2 doesn't seem to work under OS/X.

Is there a preferred way to detect that Python 2.2.1 has already been 
installed, that works for both OS9 Carbon and OS/X?
