<para>The <command>arpd</command> binary included in this package is

common requirement on a base Linux system, remove the dependency on Berkeley
DB by applying the commands below. If the <command>arpd</command> binary is
needed, instructions for compiling Berkeley DB can be found in the BLFS Book
at <ulink url="&blfs-root;view/svn/server/databases.html#db"/>.
