OK, I finally did that (I guess properly) and it worked, i.e., this works:
/System/Library/Frameworks/Python.framework/Versions/Current/bin/python ../cctbx_sources/libtbx/configure.py --compiler=gcc mmtbx
Notably, even --compiler=gcc-4.2 does not work. My guess is that invokes clang (now), whereas
llvm-g++-4.2 is invoked using --compiler
which I deduced the hard way.

The cctbx should build with the more recent versions of clang (perhaps Luc could comment on this as I think he uses clang regularly), although depending on what version of Xcode you are using, Apple used to ship a relatively old version of clang/llvm with Xcode, so clang compilation might not necessarily work straight out the box.

Same as you, i.e.,
clang --version
Apple clang version 4.0 (tags/Apple/clang-421.0.57) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin12.0.0
Thread model: posix
