[racket] Dr Racket error OS X Lion

I just upgraded to Lion (thinking I should have waited) which forced an upgrade to Racket 5.1.2. Unfortunately there is an error when you load a Racket file or type Sexp into the Dr Racket editor. I saw on the Dev list that the error is known and is already fixed in the Repo. Is there a patch somewhere that I can get or a knew executable or something? 

Thanks
Mike
