My Sinatra app won't run anymore because of these deprecation messages. The solution is in the stackoverflow thread; I tried to fork and fix this myself but alas, I'm too noobie.

I traced this down to MongoMapper by removing all references to it. The result was a running application (albeit without database data).

If someone knows an easy way to fix this..
