But only by adding a strategy for searching for packages. Those who  
don't use it will never find out.

Does it keep track of version numbers then? The Apple docs are quite  
silent about the installer.

Removing is indeed frequent only as a step in updating. There are cases  
where an update requires removing the old version first, e.g. when a  
module has been replaced by a subpackage of the same name.

Isn't that mostly because of MacPython and Fink Python being installed  
in parallel? Fink Python wouldn't be concerned at all.

That was my plan, but it's always good to check first if there are some  
evident problems that were overlooked.
