    <para>The <command>arpd</command> binary included in this package is
          dependent on Berkeley DB.  As <command>arpd</command> is not a very
          common requirement on a base Linux system we remove the dependency on
          Berkeley DB by applying the patch using the command below.  If you
          need the <command>arpd</command> binary, then instructions for
          compiling Berkeley DB can be found in the <ulink
          url="http://www.linuxfromscratch.org/blfs/view/cvs/content/databases.html#db">BLFS book</ulink>.
