Attention: Apparently since the release of 5.1.25, cluster is packaged separately. I need to do some reading and research first and then update the tutorial with the latest info.

Here are some quick links for now: http://blogs.mysql.com/kaj/2008/05/23/mysql-clusters-improved-release-model/, http://johanandersson.blogspot.com/2008/05/mysql-cluster-62-officially-released.html, http://blogs.sun.com/theaquarium/entry/improved_release_model_for_mysql.
