Now, I generally have a 5 years old notebook somewhere. I state that I
could compile a 5 years old apache with a 5 years old compiler using
a 5 years old live CD, if I have all dependent sources available.

And that's exactly one of my targets, having ALL required sources
available in the projects SVN -- apart from the notebook -- precisely
for every single version of a project. It's a kind of time machine.

But that is not the target that really matters this thread. The other
target is the interesting one, to use Prefix to get a project
initially running with a setup that is reproducable on different
machines.
