I've been away for a while, but now I'm back -- with a royal backlog. :)

On a related note, I *really* think we should move the version-numbers 
file to make/conf. I think I even have an open bug on that somewhere. 
The move itself is trivial, but the consequences needs to be checked 
carefully.

I'm happy that you put the new test-dependencies file in make/conf, though!
