Same here: if have yet to see adverse consequences of installing third  
party packages into system Python. And now that Apple is distributing  
fairly current versions of things like PyObjC there's even little  
reason to build my own copy of Python. I have one on disk, but I find  
that I use the system Python for almost everything.

Fink (and to a lesser extent MacPorts) I don't touch with a 10 feet  
pole: too often I've created software for distribution only to find  
that it somehow, behind my back, was linked against a dynamic library  
that I had installed locally through it.
