Read me error in "Install"

[finist]

For a pre rails 3.0 table_builder:
script/plugin install
git://github.com/p8/table_builder.git
cd vendor/plugins/table_builder/
git checkout pre-rails-2.2

last line need change:

git checkout pre-rails-3

Using Rails v2.3.5
I still get this error
error: pathspec 'vendor/plugins/table_builder/pre-rails-3' did not match any file(s) known to git.

Might help you to switch the tag to rails-pre-3 in github and manually download it. Just paste it in vendor/plugins/table_builder

It's really necessary run this code git checkout pre-rails-3?

I'm having this error uninitialized constant ActiveRecord::NamedScope::Scope in the line <% calendar_for(@expenses) do |calendar| %>

But I didn't run the command line above. Should I?
