[Plugin: WordPress Wiki] List of all Wiki articles on site

Using the beta version found here: wp-wiki.org – Wasn’t sure where else to post for help?

I’m trying to create a list of all the wiki pages on my site using
<?php wp_list_pages(‘title_li=&post_type=wiki’); ?>

Which displays the pages but the links are wrong. They are displaying:

website.com/wikipage
website.com/wikipage2

instead of

website.com/wiki/wikipage
website.com/wiki/wikipage2

Any suggestions to get the extra /wiki/ in there? Thanks!
