err.... yes well theres no 2011 version for mac. But yes you probably mean he should compile it himself? Well that may or may not be a valid solution, not many users out there hve a habit of doing compiles themselves.
Anyway my suggestion is if somebodey DOES compile it for mac sucessfully should post it up somewhere.
In any case its not really hard to device one of your own without resorting to a plugin the calcuation tahts used is not terribly complicated and can be replicated with expressions or utility nodes. Now all you need s a user interface for setting it up.
