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

<screen os="b"><userinput>patch -Np1 -i ../&perl-libc-patch;</userinput></screen>

   <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>

cp x2p/Makefile.SH{,.orig}
sed -e 's/miniperl/miniperl-cross/g' x2p/Makefile.SH.orig > x2p/Makefile.SH
chmod 755 utils/Makefile
