Hm, according to https://developer.apple.com/library/mac/documentation/Darwin/Conceptual/64bitPorting/transition/transition.html, 64bit OS X uses that same model as Linux, i.e. sizeof(long) == sizeof(void*). So the warning is probably caused by the fact that the typedefs Elf64_Off and uint64_t are not identical (even though the types have the same size). How are these defined on OS X?
