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

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