120    <para>The install will finish by checking that everything is correctly installed.
[5650fbe]121    Unfortunately, it will test for a multilib installation. On x86_64 Pure64 this means
[3f8be484]122    it will try to test the non-existent 32-bit loader which has a different name
123    from the 64-bit loader (unlike on other 64-bit architectures).  We fool it by
124    creating a symlink to the real loader.</para>

136    <para>Now we can remove this symlink.  We also need to correct the <command>

138    not only the 32-bit linker, but also /lib64 where it thinks the 64-bit linker
[39139e4]139    is. The following <command>sed</command> will correct this:</para>

174    <para>By default, the dynamic loader (<filename
175    class="libraryfile">/lib/ld-linux-x86-64.so.2</filename>) searches through
176    <filename class="directory">/lib</filename> and <filename
177    class="directory">/usr/lib</filename> for dynamic libraries that are
178    needed by programs as they are run. However, if there are libraries in
179    directories other than <filename class="directory">/lib</filename> and
180    <filename class="directory">/usr/lib</filename>, these need to be
181    added to the <filename>/etc/ld.so.conf</filename> file in order
182    for the dynamic loader to find them. Two directories that are commonly
183    known to contain additional libraries are <filename
184    class="directory">/usr/local/lib</filename> and <filename
185    class="directory">/opt/lib</filename>, so add those directories to the
186    dynamic loader's search path.</para>
