    <title>Installation of Readline</title>

    <para>Reinstalling Readline will cause the old libraries to be moved to
    &lt;libraryname&gt;.old. While this is normally not a problem, in some cases
    it can trigger a linking bug in <command>ldconfig</command>. This can be
    avoided by issuing the following two seds:</para>

<screen><userinput remap="pre">sed -i '/MV.*old/d' Makefile.in
sed -i '/{OLDSUFF}/c:' support/shlib-install</userinput></screen>

    <para>Now fix a problem identified upstream:</para>

<screen><userinput remap="pre">patch -Np1 -i ../&readline-fixes-patch;</userinput></screen>

    <para>Prepare Readline for compilation:</para>

<screen><userinput remap="configure">./configure --prefix=/usr    \

          <para>This option tells Readline that it can find the termcap
          library functions in the curses library, not a separate
          termcap library. This will generate the correct
          <filename>readline.pc</filename> file.</para>
