      <para>There are two package files whose name starts with

    <para>This package first builds the Python interpreter, then some
    standard Python modules. The main script for building modules is
    written in Python, and uses hard-coded paths to the host <filename
    class="directory">/usr/include</filename> and <filename
    class="directory">/usr/lib</filename> directories. To prevent them
    from being used, issue:</para>
