Using macports on MacOS 10.7, I did a quick build (without worrying about LLVM)

With JIT

        A = gen_test (1000000);
        K = 500;
        Vectorized: 1.274 sec
        Loopy: 4.875 sec

With 3.7.0+

        A = gen_test (1000000);
        K = 500;
        Vectorized: 5.944
        Loopy: 16.063

I'll try again with LLVM_CONFIG=/opt/local/bin/llvm-config-mp-3.0
