I just installed a newer version of Ubuntu and so with it, rails  
2.3.2. Now I can’t get acts\_as\_list working. I get the error:

undefined method `acts\_as\_list’ for Child(Table doesn’t exist):Class

But I have already run

> ruby script/plugin install acts\_as\_list

- ./README
- ./init.rb
- ./lib/active\_record/acts/list.rb
- ./test/list\_test.rb

I started a new program that had nothing but the creation of a class  
that uses acts\_as\_list. Can somebody please help?
