whiny_finder in Rails 2.0

Hello -

I have upgraded to Rails 2.0. I am still fixing from plugins related
issues...the latest one I have is with whiny_finder

I have the following error:
undefined method `find_by_url!' for #<Class:0x2443aac>

It can't find the find_by_url! or find_by_<filed>! method.

I am struggling to find a solution. Any help?
