    If this is your first install, automatically load on login with:
        mkdir -p ~/Library/LaunchAgents
        cp #{prefix}/org.freedesktop.dbus-session.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/org.freedesktop.dbus-session.plist

    If this is an upgrade and you already have the org.freedesktop.dbus-session.plist loaded:
        launchctl unload -w ~/Library/LaunchAgents/org.freedesktop.dbus-session.plist
        cp #{prefix}/org.freedesktop.dbus-session.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/org.freedesktop.dbus-session.plist
    EOS
  end
