Both of these should be fine and are modern enough for developing using DMD.

If you run "make -f posix.mak" it will build only build for the default 
architecture, that is most likely 64bit. Only 64bit binaries of DMD are 
distributed. For Phobos a universal (fat) binary is distributed. Search 
for "lipo" in the Phobos makefile. lipo is the tool used to combine 
multiple architectures to a single binary. You can verify the result by 
running "file path/to/binary". It will tell which architectures are 
available in the binary. These tools work both with executables, dynamic 
and static libraries.

The developer tools, aka Xcode, available in App Store.
