DEPRECATION WARNINGs

Hello, new to rails, I'm currently learning Rails 3 using the online
book. Whenever I run a rails command in terminal, the results are
always proceeding by:

DEPRECATION WARNING: railtie_name is deprecated and has no effect.
(called from /Library/Ruby/Gems/1.8/gems/will_paginate-3.0.pre/lib/
will_paginate/railtie.rb:6)

How does a Rails developer resolve this? thxs

This is (was) the issue with will_paginate -
http://github.com/mislav/will_paginate/issues/issue/36

I would suggest to try using will_paginate-3.0.pre2 as it seems fixed
there.

thank you!
