I still don't get what your point is.

To build any D application (which might be a D compiler or not), 
you need a D compiler on your host system. This D compiler will 
come with druntime, Phobos and any number of other libraries 
installed.

Now, if the application you are building using that host compiler 
is DMD, you will likely use that new DMD to build a (newer) 
version of druntime and Phobos later on. But this doesn't have 
anything to do with what libraries of the host system the 
application can or can't use.

No fork in sight anywhere.
