I've had the same problem when trying to compile a shared 
library, but with dmd.

It turned out that to make a shared library you can't use phobos 
dependencies because it isn't ready to work with shared 
libraries. Indeed, if you remove any phobos dependencies, the 
shared library is compiled successfully.

Well, that's the noob explanation, I don't know the details of 
why phobos doesn't work. My bet is that it is shipped as a static 
library, and (if I'm not wrong) you can't link a static library 
on a shared library...

Still, that is a big problem that D has.
