<para>The following patch fixes various issues including a problem where Readline
sometimes will only show 33 characters on a line and then wrap to the next line.</para>

<screen><userinput>patch -Np1 -i ../readline-&readline-version;-fixes-1.patch</userinput></screen>

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

<screen><userinput>./configure --prefix=/usr</userinput></screen>

<para>Compile the package:</para>

<screen><userinput>make SHLIB_XLDFLAGS=-lncurses</userinput></screen>

<para>Install the package:</para>

<screen><userinput>make install</userinput></screen>

<para>Give Readline's dynamic libraries to a more appropriate permissions:</para>

<screen><userinput>chmod 755 /usr/lib/*.&readline-version;</userinput></screen>

<para>And move them to a more appropriate location:</para>

<screen><userinput>mv /usr/lib/lib{readline,history}.so.5* /lib</userinput></screen>

<para>Because the libraries have been moved, a few symlinks are now pointing to
non-existent files. Recreate those symlinks:</para>

<screen><userinput>ln -sf ../../lib/libhistory.so.5 /usr/lib/libhistory.so
ln -sf ../../lib/libreadline.so.5 /usr/lib/libreadline.so</userinput></screen>
