    <<-EOS.undent
      Homebrew has NOT installed npm. We recommend the following method of
      installation:
        curl http://npmjs.org/install.sh | sh

      After installing, add the following path to your NODE_PATH environment
      variable to have npm libraries picked up:
        #{HOMEBREW_PREFIX}/lib/node_modules
    EOS
  end
