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

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

    <screen><userinput>rm -v /lib/ld-linux.so.2
cp -v /usr/bin/ldd{,.bak}
sed '/RTLDLIST/s%/ld-linux.so.2 /lib64%%' /usr/bin/ldd.bak >/usr/bin/ldd</userinput></screen>

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

    <screen><userinput>rm -v /usr/bin/ldd.bak</userinput></screen>
