These are not compatible. You have installed python.org's macosx10.6 
installed (a very reasonable choice). But you must install binary 
packages labelled 10.6, never packages labelled 10.3 (which are only for 
the 10.3 version of python.org's python).

I'm glad you got an error message (however opaque), since if the install 
had succeeded the results would not have worked.

P.S. the difference is:
- 10.6 (which requires MacOS X 10.6 or later) is 64-bit and requires 
intel
- 10.3 (which requires MacOS X 10.3.9 or later) is 32-bit and includes 
PPC support
