Currently there must be a place where druntime finds dmd for building 
purposes. Also phobos needs to find druntime. Also dlang.ord needs to 
find the source of both phobos and druntime.

There's no specific setup of one person as much as a boring:

/some/dir/
   dmd
   druntime
   phobos
   dlang.org
   tools

I have a hard time making it any simpler.

Where would that super-repo sit?
