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

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

153 <para>Check the script to make sure the sed worked correctly, then delete
154 the backup.</para>

191 <para>By default, the dynamic loader (<filename
192 class="libraryfile">/lib/ld-linux-x86-64.so.2</filename>) searches through
193 <filename class="directory">/lib</filename> and <filename
194 class="directory">/usr/lib</filename> for dynamic libraries that are
195 needed by programs as they are run. However, if there are libraries in
196 directories other than <filename class="directory">/lib</filename> and
197 <filename class="directory">/usr/lib</filename>, these need to be
198 added to the <filename>/etc/ld.so.conf</filename> file in order
199 for the dynamic loader to find them. Two directories that are commonly
200 known to contain additional libraries are <filename
201 class="directory">/usr/local/lib</filename> and <filename
202 class="directory">/opt/lib</filename>, so add those directories to the
203 dynamic loader's search path.</para>
