You need to delete the src/phobos/object.d.  Then 
src/druntime/import/object.di is included instead and everything starts 
to work (for some simple projects at least).  Building druntime.lib 
doesn't seem to be required.

I think it's also a good idea to delete src/phobos/std/gc.d because it's 
not in the libs.  You have to use core.memory instead.
