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>

144
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>
149
150    <screen><userinput>rm -v /lib/ld-linux.so.2
151cp -v /usr/bin/ldd{,.bak}
152sed '/RTLDLIST/s%/ld-linux.so.2 /lib64%%' /usr/bin/ldd.bak >/usr/bin/ldd</userinput></screen>
153
154    <para>Check the script to make sure the sed worked correctly, then delete
155    the backup.</para>

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