joomla integration problem

hi all. i'm trying to integrate punBB into joomla as module. I don't want to use wrapper because of possible search engines problems. Also, wrapper auto height doesn't work in Opera.

punBB installed into "/forums/"  and joomla - in root folder.

What code should I writhe into module to get the forums work? I've tried

include('./forums/index.php');

and

include('/home/public_html/forums/index.php');

and so on (without http, because my hoster doesn't allowed direct urls), but getting various errors.

could someone help me and tell what exacly should I writhe, to ghet forum work, please?

Thanks
