    <para os="a">First adapt some hard-wired paths to the C library by applying
    the following patch:</para>

   <para os="c">Now make a change to allow the creation of a cross-compiled version of
   perl. This change will rename miniperl to miniperl-cross. The files that need to be modified also need their permissions changed:</para>
