Trouble updating to Rails 2.0

I recently updated my gems and first I got an error with Rails.

Aparently, Rails 2.0 has a dependency on ActiveResource, but the gems
dont install it as a dependency. At least not when upgrading from
1.2.6 to 2.0

Then, when I try to freeze the gems to generate the new documentation,
I get the following error:

gabriel@fenix:~/dummy$ rake rails:freeze:gems --trace

Am I missing something or the rails 2.0 gems are missing something?
Gems version is 0.9.5

Yeah, I get the same error. The freeze:gem task is broken

A workaround is to just use this command:
svn export http://dev.rubyonrails.org/svn/rails/tags/rel_2-0-1/ vendor/
rails
