At least Gentoo tries to mirror the sources (still, why not fetch them _only_ 
from the distfiles mirrors?), other source-based distributions won't even 
bother doing that.

Oh, I didn't know about that tool. But why do you have to do that by hand? It 
should be automatic. Yum or apt won't update a library without also updating 
the applications which depend on it to versions built against the correct 
library.

I don't know why I couldn't remember the specific term, I knew it of 
course. :-) But ebuilds, specfiles etc. are all "recipes". ;-)
