<= 2.067 does not require a host D compiler at all to build.
master requires a host D compiler (but not a very recent one)
Building ddmd requires >= 2.067

So for now, you just need _a_ compiler to build dmd.  If you want to build ddmd you will need to upgrade to 2.067.

After the 2.067 release I will start adding ddmd stuff to master, but even then you will still be able to build the C++ version of dmd with most old versions of dmd2 as host compiler.
