hmm, If I install python1.5-examples, I would expect, that the
examples run with python1.5; same for python2.1-examples. So yes, if I
have a legacy python1.5-numeric package, I tend to call python1.5
explicitely.
The source modification can be made at package build time, so that is
not problematic.

IMO Using "#!/usr/bin/env pythonX.Y" is maybe necessary for some
scripts.
