I haven't done this personally so I can only guess but...

Did you follow these instructions? ie did you logout and then restart 
the shell window - ie Terminal?

If so and it didn't work try running the env command

Look for the PATH entry and see whether Python 2.5 comes before Python 3.1.

If so you probably need to edit your ~/.profile or ~/.bashrc or ~/.cshrc 
depending which shell you use.
