Custom group by pagination and a calculated field

This is a basic example of how to use the CakePHP paginator helper with the group by condition, it took a little mucking around but this is how I got it working.

In this example we have a Comment controller which I want to paginate a custom query displaying an IP address and a calculated count field of the number of spam comments from this particular IP address...
