I do know that c programs can be dynamically linked and most of the time on 
unixes they seem to be. But it seems to be far too common that the library 
changes in some way that requires that the program be recompiled. I have seen 
it with both kde and gnome where just recompiling them with no changes to 
their code at all fixed library problems that where being reported.

I have never seen that kind of thing in python.

I don't know why they break. I know that they do.

Well in my world everything is written for unixes and deployed on unixes and 
most of them are linux boxes which have good package systems.
