I agree with Jeff that this shouldn't have happened, or should at the very least
have been documented in the release notes for 2.6.3. I know of several users
of Python that have been bitten by this (they installed 2.6.3 and now easy_install
doesn't work anymore for them).  

For beginners this issue is a showstopper that they cannot resolve without help.

This is a problem, it means 2.6.3 is not a simple drop-in replacement for 2.6.2 but requires the replacement of another component as well.  That can be a problem in organizations with strict configuration management where you cannot install new software without going to lots of red tape (and that might involve lawyers when you install a new package instead of upgrading an existing one).
