I would point out that every time I've seen compiler devs discuss 
using Phobos in dmd, there has been a large reluctance to do so 
(if not outright a desire to avoid it entirely) in order to avoid 
the circular dependencies that would ensue (Daniel Murphy in 
particular really doesn't seem to like the idea). It's much 
easier to control what's going on with dmd if it doesn't rely on 
Phobos. So, while it may very well be that ddmd eventually uses 
Phobos, I suspect that you have an uphill battle in trying to 
make it happen. It's more likely that ddmd would end up with some 
simplified copies of the necessary functionality from Phobos 
within its own source code in order to avoid any such 
dependencies.
