Not sure what's the "right" approach, but you could try compiling with dmd -v to find the path(s) to the runtime libraries that you'll need to link. Keep in mind that before calling any non-trivial D code (i.e., that uses the GC or any druntime function, including language hooks) you need to call core.runtime.rt_init first. And preferably at shutdown call core.runtime.rt_term to cleanup. Not sure what will happen if more than one D library does this, though. My guess is that you'll somehow need to get them all to link to (or otherwise be aware of) a single instance of the D runtime, otherwise you might get some weird runtime behaviour when the two runtimes conflict with each other.
