I don't think that is quite the case. The standard approach that distributions 
use for this kind of problem is to make it possible to install the old 
version along side the new one. This is very common for shared libraries for 
example.

I am fairly sure that that is not how Debian handles Python these days. They 
phase in support for newer Python versions and modules, while maintaining the 
older packages for any software that needs them. Right I use Python 2.4 and I 
can also install packages for 2.3 or 2.5, and use the them at the same time.

The "parallel installation" trick doesn't work for SIP inside the same Python 
version.

The reason why I'm busying myself with this whole issue is because KDE 4 is 
coming and little has been communicated about Python and PyKDE in the KDE 
community. I've been talking to Jim about his plans for PyKDE, and once I've 
got some of the details worked out I'll be promoting PyKDE a bit to the 
KDE "core" developers and anyone else who will listen. :-)
