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

143
144    <para>Now we can remove this symlink.  We also need to correct the <command>
145    /usr/bin/ldd</command> script - if you look at this, you will see it references
146    not only the 32-bit linker, but also /lib64 where it thinks the 64-bit linker
147    is. The following <command>sed</command> will correct this:</para>
148
149    <screen><userinput>rm -v /lib/ld-linux.so.2
150cp -v /usr/bin/ldd{,.bak}
151sed '/RTLDLIST/s%/ld-linux.so.2 /lib64%%' /usr/bin/ldd.bak >/usr/bin/ldd</userinput></screen>
152
153    <para>Check the script to make sure the sed worked correctly, then delete
154    the backup.</para>

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