IDLE doesn't run on OSX 10.3.9

[thomascribbs at gmail.com]

Just installed Python 2.5.2 on a PowerPC G4 running OSX 10.3.9 and
when clicking on the IDLE icon  in the MacPython 2.5 folder nothing
happens, program doesn't execute...

I've uninstalled, reinstalled over again...

I friend of mine just installed the same 2.5.2 download from the
Python.org website on OSX 10.4.11 and all went fine...but shouldn't it
install on 10.3.9 as well?

Anyone have any ideas?  Thanks.
