    <para>The <command>arpd</command> binary included in this package is
    dependent on Berkeley DB.  Because <command>arpd</command> is not a very
    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-book;server/databases.html#db"/>.

    <para>This package comes with a test suite, but due to assumptions it makes,
    it is not possible to reliably run these tests from within the chroot
    environment. If you wish to run these tests after booting into your new LFS
    system, ensure you enable <filename>/proc/config.gz</filename> support
    in your kernel (&quot;General setup&quot; -> &quot;Enable access to
    .config through /proc/config.gz&quot; [CONFIG_IKCONFIG_PROC]), then run
    'make alltests' from the <filename class="directory">testsuite/</filename>
