Mac - Blender crashing instantly

I have just downloaded the latest version of blender and I cant get it to open. I saw something mentioned about it in the FAQs and did the command line thin with the following result

dyld: Library not loaded: /Library/Frameworks/Python.framework/Versions/2.4/Python
Referenced from: /Applications/blender-2.40-OSX-10.3±py2.4-powerpc/
Reason: image not found
Trace/BPT trap

Can anybody suggest something here?
also am I meant to download some sort of Python framework or something as it seems to say in the error message because I cant find anything online and blender does not install anything.

Couple of other threads about it:
