log4r warning message...

I installed log4r as a gem on Max OS X Leopard. When I start the
server locally, I have a warning that I'd like to get rid of. I think
this is a side-effect of log4r? Other rails projects that I am working
on, on the same machine that don't generate this warning. this one is
the only one using log4r.
