PHP4 to PHP5 issue

Hey all, I installed a new FreeBSD 6.0 server here in the office with PHP5. I moved over several sites we developed under PHP4, and all of those seem to be functioning perfectly, but I am getting an error on to sites, on PostNuke based and our dotProject system. Both errors are the same, and here is the one from dotProject: Fatal error: Call to a member function Execute() on a non-object in /usr/home/dotproject/public_html/classes/query.class.php on line 589 And the code: $this->_query_id = $db->Execute($q); Where $q is a pretty typical SQL statement. What I'm wondering if there is an easy way to convert $q to an object type rather than a string to satisfy Execute? Or some other straightforward fix? Thanks!
