But this is weird - a release being built is required for building, um, 
itself?

I do understand that idgen is a separate executable but the simple view 
is that if dmd 2.067 requires dmd being present, the preexisting dmd 
can't be 2.067.

Or I'm misunderstanding something. The short version is the simpler the 
bootstrapping the better.
