Is this a problem? Bummer. I always thought the reason the patch release
number wasn't included in the path was that this didn't matter, so I'll
assume this is due to strange linker issues I avoid by refusing to write
any code that needs to be compiled :-)

If 2.3.3 runs modules from 2.3.0, but not vice versa, it would be 
possible
to add both ~/Library/Python/2.3.x/site-packages *and*
~/Library/Python/2.3/site-packages to the python path, in decending 
order.
So a module installed using Python 2.3.0 would be available to Python 
2.3.3.
There might be some user confusion when a package installed with 2.3.0
is upgraded with 2.3.3 , but the net gain might be positive.

I'm probably totally misunderstanding this area, but I did notice that
the Python documentation never appeared in the help viewers Library
menu until after it had been launched the first time (so it may simply
be a case of installing the new help files, and then telling the
Help View to open then from this new path).
