Upgrading an app to Rails 3.1.0.beta1

I'm attempting to update my existing rails app (3.0.3) to 3.1.0.beta1. I've install the rails gem and ran the bundle command to pull in all of the updated gems. When I run rake rails:update though I get:

rake aborted!
undefined method `join_asset_file_contents' for module `ActionView::Helpers::AssetTagHelper'

What am I doing wrong?

Trace Output

join_asset_file_contents method is moved from

actionpack/lib/action_view/helpers/asset_tag_helper.rb

to

actionpack/lib/action_view/helpers/asset_tag_helpers/asset_include_tag.rb

That is the reason why you see this error.

Can you please run the rake command with --trace to see why join_asset_file_contents is being executed in the call graph?
