CC is generically the variable used to hold path to the compiler
g++ is (usually) a symlink to llvm-g++
llvm-g++ is the hybrid gcc frontend / llvm backend compiler

We fully intend to switch completely to the clang compiler (llvm frontend and backend) on Lion, however for SnowLeopard, the supported compiler will likely have to remain LLVM-GCC.

More info on LLVM here: <http://llvm.org/>, and clang specifically here: <http://clang.llvm.org/>.
