On the Extensions tab, it says:

The jquery.datepick.ext.js module provides additional functionality to extend the datepicker

(emphasis added).

And looking in the downloads, there does appear to be a file of that name included. But you're only using jquery.datepick.js

So try:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="js/jquery.datepick.js"></script>
<script type="text/javascript" src="js/jquery.datepick.ext.js"></script>
