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

138    <para>Now we can remove this symlink.  We also need to correct the <command>
139    /usr/bin/ldd</command> script - if you look at this, you will see it references
140    not only the 32-bit linker, but also /lib64 where it thinks the 64-bit linker
141    is. The following <command>sed</command> will correct this:</para>

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

186    <filename class="directory">/lib</filename> and <filename
187    class="directory">/usr/lib</filename> for dynamic libraries that are
188    needed by programs as they are run. However, if there are libraries in
189    directories other than <filename class="directory">/lib</filename> and
190    <filename class="directory">/usr/lib</filename>, these need to be
191    added to the <filename>/etc/ld.so.conf</filename> file in order
192    for the dynamic loader to find them. Two directories that are commonly
193    known to contain additional libraries are <filename
194    class="directory">/usr/local/lib</filename> and <filename
195    class="directory">/opt/lib</filename>, so add those directories to the
196    dynamic loader's search path.</para>
