    <para><option>--enable-shared</option>: This switch will ensure
    that shared, as well as static, libraries will be built. If you
    have linked the packages which use these libraries
    (<application>gnutls</application> and
    <application>glib-networking</application>, perhaps others) to the
    shared libraries, and ever have to rebuild
    <application>libnettle</application> to fix a vulnerability, you
    will not have to recompile those other applications.</para>
