Problems with jruby 1.6.5

[asdavey]

There appears to be a problem running the cantango install generator with Rails 3.1.0 and JRuby 1.6.5. When you run rails g cantango:install an error occurs. I got the same error on both Ubuntu and WIndows 7. I've included steps to reproduce for Ubuntu.

Steps to Reproduce

1. rvm install jruby-1.6.5
2. rvm gemset create rails310
3. rvm use jruby-1.6.5@rails310
4. export JRUBY_OPTS=--1.9
5. Run jruby -v, and the version should return jruby 1.6.5 (ruby-1.9.2-p136)
6. gem install rails -v 3.1.0
7. rails new test_app
8. cd test_app
9. Add "gem 'cantango'" to Gemfile
10. bundle install
11. rails g cantango:install

What I expected to happen

I expected that a cantango.rb file would be generated in the config/initializers folder.

What happened instead

Instead I got the following error message:

TypeError:  is not a class/module

[venomizer]

Was this issue ever resolved?

[asdavey]

I can't really say. I decided not to use cantango for my particular problem.

[venomizer]

Yeah, seeing as how Cantango doesn't seem to have any support anymore, I dropped it from my app too.
