Looking for help overriding clear_old_version in acts_as_versioned

For a new rails app I'd to utilize a combination of acts_as_versioned and acts_as_paranoid to allow me to track the lifespan of objects (a real client need).

So far it's working fairly well except that when I destroy an Active Record object the acts_as_versioned plugin is deleting all of the old versions. It's using a method called clear_old_version and in the docs it says:


Clears old revisions if a limit is set with the :limit option in acts_as_versioned. Override this method to set your own criteria for clearing old versions.

My question is: How do I override it. I added a method to my Active Record model but I don't think it's getting called. Perhaps it's because this clear_old_version is burried in a stack of Modules.

Any help is appreciated. Thanks.
