    To install the zmq gem on 10.6 with the system Ruby on a 64-bit machine,
    you may need to do:

        ARCHFLAGS="-arch x86_64" gem install zmq -- --with-zmq-dir=#{HOMEBREW_PREFIX}

    If you want to build the Java bindings from https://github.com/zeromq/jzmq
    you will need the Java Developer Package from http://connect.apple.com/
