RubyAMF methods not being found - plugin not being included?

Hi, Im trying to use rubyAMF, and I installed the plugin into my
vendor/plugins directory.

However, it doesnt seem to be loading the active_record and
action_controller utilities.

There is a method in rubyAMF called “as_single!” This method is not
being found in AR. Looking through the plugin code, I dont see how the
file gets required since there is no “init.rb” file in the main
directory.

Has anyone seen this?
