    <p>There is no known workaround at this time.</p>

  <resolution>
    <p>Gentoo has discontinued support for PyCrypto. We recommend that users
      unmerge PyCrypto:
    </p>
    
    <p># emerge --unmerge “dev-python/pycrypto”</p>
    
    <p>NOTE: The Gentoo developer(s) maintaining PyCrypto have discontinued
      support at this time. PyCryptodome is the canonical successor to
      PyCrypto.
