  <title>Host System Requirements</title>

    <para>You should be able to build a CLFS system from just about any
    Unix-type operating system. Your host system should have the following
    software with the minimum versions indicated. Also note that many
    distributions will place software headers into separate packages, often in
    the form of <quote>[package-name]-devel</quote> or
    <quote>[package-name]-dev</quote>. Be sure to install those if
    your distribution provides them.</para>
