  <resolution>
    <p>Gentoo has discontinued support for ssvnc. We recommend that users
      unmerge ssvnc:
    </p>
    
    <code>
      # emerge --unmerge "net-misc/ssvnc"
    </code>
    
    <p>NOTE: The Gentoo developer(s) maintaining ssvnc have discontinued
      support at this time. It may be possible that a new Gentoo developer will
      update ssvnc at a later date. An alternative may be a manual SSH tunnel.
    </p>
