Apple does not provide upstream patches, so Binutils and GCC will
likely have gaps. Plus, Apple has moved on to LLVM/Clang. Its why, for
example, GCC is stuck at 4.2 and gdb-7.x does not work as expected on

Your best would probably be to download "Command Line Tools" from
Apple. I believe its available at, but you have to
be logged in as a developer to see them. Apple offers a free Xcode,
and I believe you can download Command Line Tools from Xcode's
Preferences -> Downloads.

I'm not trying to talk you out of building Binutils/GCC. I'm just
pointing out you will encounter hardships and difficulties.
