147    <para>By default, the dynamic loader (<filename
148    class="libraryfile">/lib/ld-linux.so.2</filename>) searches through
149    <filename class="directory">/lib</filename> and <filename
150    class="directory">/usr/lib</filename> for dynamic libraries that are
151    needed by programs as they are run. However, if there are libraries in
152    directories other than <filename class="directory">/lib</filename> and
153    <filename class="directory">/usr/lib</filename>, these need to be
154    added to the <filename>/etc/ld.so.conf</filename> file in order
155    for the dynamic loader to find them. Some directories that are commonly
156    known to contain additional libraries are
157    <filename class="directory">/usr/local/lib</filename>,
158    <filename class="directory">/usr/local/lib64</filename>,
159    <filename class="directory">/opt/lib</filename>,
160    and <filename class="directory">/opt/lib64</filename>,
161    so add those directories to the dynamic loader's search path.</para>
