There is no equivalent to DllMain on OS X or Posix for that 
matter. The closest you get is the GCC/Clang attribute 
__attribute__((constructor)), but that requires using a C file, 
if not LDC or GDC supports that attribute.

Just for the record, dynamic libraries doesn't work yet on OS X 
in D. At least not properly. This might be the reason why shared 
static this() isn't called.
