120 <para>The install will finish by checking that everything is correctly installed.
121 Unfortunately, it will test for a multilib installation. On x86_64 Pure64 this means
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>

135
136 <para>Now we can remove this symlink. We also need to correct the <command>
137 /usr/bin/ldd</command> script - if you look at this, you will see it references
138 not only the 32-bit linker, but also /lib64 where it thinks the 64-bit linker
139 is. The following <command>sed</command> will correct this:</para>

142sed -i.bak '/RTLDLIST/s%/ld-linux.so.2 /lib64%%' /usr/bin/ldd</userinput></screen>
143
144 <para>Check the script to make sure the sed worked correctly, then delete
145 the backup.</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>
