Certainly, this doesn't have a "major impact on the usability" of this 
package?

Offhand, it seems kind of silly that a Python package needs to ask cdbs 
for the current Python version.  Perhaps it would make more sense if 
the unversioned "python" package provides a link to the current 
version?  Something like

/usr/lib/python/doc/tools/ -> /usr/lib/python2.4/doc/tools/

or even

/usr/lib/python/ -> /usr/lib/python2.4/

I'm not against this change, but it seems to attack the problem from the 
wrong end.
