    Hi Bill,<br>
    <br>
    Sorry that i just notice this email, sorry for the late reply.<br>
    <br>
    I made this patch based on the following two points:<br>
    1. Please see commit 467eb93f and 84a39786, there has the following
    code in files automake_1.15.bb and autoconf.inc:<br>
        CACHED_CONFIGUREVARS += "ac_cv_path_PERL=${USRBINPATH}/perl"<br>
    2. The familiar modifications for other files are accepted by
    oe-core, like gobject-introspection groff texi2html quilt and so
    on...<br>
    <br>
    Thanks,<br>
    Zhenbo<br>
