154    <para>By default, the dynamic loader (<filename

156    <filename class="directory">/lib</filename> and <filename
157    class="directory">/usr/lib</filename> for dynamic libraries that are
158    needed by programs as they are run. However, if there are libraries in
159    directories other than <filename class="directory">/lib</filename> and
160    <filename class="directory">/usr/lib</filename>, these need to be
161    added to the <filename>/etc/ld.so.conf</filename> file in order
162    for the dynamic loader to find them. Two directories that are commonly
163    known to contain additional libraries are <filename
164    class="directory">/usr/local/lib</filename> and <filename
165    class="directory">/opt/lib</filename>, so add those directories to the
166    dynamic loader's search path.</para>
