108    <para>The install will finish by checking that everything is correctly installed.
109    Unfortunately, it will test for a multilib installation. On x86_64 Pure64 this means
110    it will try to test the non-existent 32-bit loader which has a different name
111    from the 64-bit loader (unlike on other 64-bit architectures).  We fool it by
112    creating a symlink to the real loader.</para>

161    <para>By default, the dynamic loader (<filename
162    class="libraryfile">/lib/ld-linux-x86-64.so.2</filename>) searches through
163    <filename class="directory">/lib</filename> and <filename
164    class="directory">/usr/lib</filename> for dynamic libraries that are
165    needed by programs as they are run. However, if there are libraries in
166    directories other than <filename class="directory">/lib</filename> and
167    <filename class="directory">/usr/lib</filename>, these need to be
168    added to the <filename>/etc/ld.so.conf</filename> file in order
169    for the dynamic loader to find them. Two directories that are commonly
170    known to contain additional libraries are <filename
171    class="directory">/usr/local/lib</filename> and <filename
172    class="directory">/opt/lib</filename>, so add those directories to the
173    dynamic loader's search path.</para>
