  def caveats; <<-EOS.undent
    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 later build the Java bindings from https://github.com/zeromq/jzmq,
    you will need to obtain the Java Developer Package from Apple ADC
    at http://connect.apple.com/.
