To run ILIAS 3 you will need the following missing PEAR components:
<ul>
<?php
        if (!$pear) echo "<li>PEAR</li>";
        if (!$auth) echo "<li>Auth</li>";
        if (!$html_templ_it) echo "<li>HTML_Template_IT</li>";

        if (!$mdb2_mysql) echo "<li>MDB2#mysql</li>";
?>
</ul>
You can find help on how to install the missing components
