<para>The Bzip2 package does not contain a <command>configure</command>

script. There are two <filename>Makefile</filename>, one for the shared

library, and the other for the static library. Since we need both, We

do the compilation in two stages. First the shared library:</para>

<para>This will cause Bzip2 to be built using a different

<filename>Makefile</filename> file, in this case the

<filename>Makefile-libbz2_so</filename> file, which creates a dynamic
