With rpath being a linker concept, there isn't really such a thing as a
compiler not supporting "rpath stuff". Proper shared library support in
D needs support code in druntime to integrate with the garbage
collector, thread initialization, etc. To my knowledge, DMD currently
doesn't do any of that on OS X.
What has changed somewhat recently is the way DMD implements TLS on OS
X. Now it uses the default system facilities for it, which makes it
easier to integrate with shared libraries (but requires 10.7+).
Basically, all that is needed is somebody to sit down and port my work
for LDC to DMD.

To my knowledge, it doesn't, and hasn't been developed or tested for OS
X for a while now.

Indeed – if you are after full platform support, LDC is probably the
compiler of choice.
