Weird Issue with rspec and authlogic-openid

I’ve been playing around rspec in my application which also uses AuthLogic’s OpenID.  When doing

rake spec 

I get the following, very weird error:

(in /Users/Michael/r/wc)
/Users/Michael/.gem/ruby/1.8/gems/activerecord-2.3.2/lib/active_record/base.rb:1964:in `method_missing': undefined method `config' for #<Class:0x263efdc> (NoMethodError)
from /Library/Ruby/Gems/1.8/gems/authlogic-oid-1.0.3/lib/authlogic_openid/acts_as_authentic.rb:35:in `optional_fields='
from /Users/Michael/r/wc/app/models/user.rb:3
from /Library/Ruby/Gems/1.8/gems/authlogic-2.0.13/lib/authlogic/acts_as_authentic/base.rb:37:in `acts_as_authentic'
from /Users/Michael/r/wc/app/models/user.rb:2
from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'

As seen above I’m using version 1.0.3 of the source code.  For the life of me, I couldn’t figure out what was wrong.  What was even stranger was the code was working when running the site.  It turns out, config got changed to rw_config, and the gem repository at rubyforge hasn’t been updated to the latest 1.0.4 which includes this change:

Change from using config to the new rw_config. Requires the latest version
of authlogic. config was too general of a name and was causing conflicts
for people in their own projects.

So I changed the acts_as_authentic.rb file so config is named rw_config, and everything worked fine.

I’d love to find a good reference on how rspec loads gems, and why this isn’t an issue when running the site.  I’m also interested in knowning how to pull content as a gem from github source (the openid gem isn’t at gems.github.com).

2. Getting Ruby 1.9, Readline, Rails, and Mysql all running on Snow Leopard
3. Great Site for the Ruby on Rails API
