It looks like you've installed a local copy. By default, I seem to 
remember, Python installs with a prefix of /usr/local, so if you have 
/usr/local/bin on your PATH variable you will pick up a local copy in 
preference to the standard version installed with the OS.

Try running

   /usr/bin/python

and see if that original one is still there (which it probably will be). 
Id so, all you need to do is uninstall the local version and things will 
magically return to normal.
