Rails 2.3.9, adding ActiveScaffold, getting in `alias_method': undefined method `number_of_pages' for class `Paginator'

Question

Hi,

I have AS working in another app just fine (I dont remember this issue...) - its also using Rails 2.3.9, on same dev box.

Now trying to add it to a new app and getting this error when running the webrick, script/server:

/Users/kimptoc/.rvm/gems/ruby-1.8.7-p302/gems/activesupport-2.3.9/lib/
active_support/core_ext/module/aliasing.rb:33:in `alias_method':
undefined method `number_of_pages' for class `Paginator' (NameError)
        from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p302/gems/
activesupport-2.3.9/lib/active_support/core_ext/module/aliasing.rb:
33:in `alias_method_chain'
        from /Users/kimptoc/Documents/ruby/borisbikestats/vendor/plugins/
active_scaffold/lib/extensions/paginator_extensions.rb:9

I couldn't find any previous references to this error.

Thanks in advance for any pointers as to what I am doing wrong.

Thanks, Chris
