I cannot figure out why rails/ruby cannot see this gem, despite each telling me that the gem is visible. I compiled this gem locally from a github branch since the main version seems to be broken in Rails 3. Or perhaps I am missing something else entirely.

Can anyone explain why this might be happening? I'd really appreciate it!
** UPDATE -- Response to Andrew Marshall's suggestion**
I changed Gemfile to read the gem directly from git, but it did not resolve the problem. Does this mean that there is a problem with this gem? The error message is not very helpful ;-)
Removed:
Ovid:lightserve dlipa$ bundle show acts_as_list
Could not find gem 'acts_as_list' in the current bundle.
Then added back via:
gem "acts_as_list", :git => "git://github.com/vpereira/acts_as_list.git"
Ovid:lightserve dlipa$ bundle install
Updating git://github.com/vpereira/acts_as_list.git
...
Same problem even though bundle show matches the commit on that page:
Ovid:lightserve dlipa$ bundle show acts_as_list
/Users/dlipa/.rvm/gems/ruby-1.9.2-p180/bundler/gems/acts_as_list-4cb76a8b198c
Ovid:lightserve dlipa$ irb
ruby-1.9.2-p180 :001 > require 'acts_as_list'
LoadError: no such file to load -- acts_as_list
from /Users/dlipa/.rvm/rubies/ruby-1.9.2-..
I just looked in the gem and it appears there is no file called 'acts_as_list' in the gem. So it appears to be idiosyncratic, albeit poorly reported by Rails/Ruby.
The API appears to have changed to:
ruby-1.9.2-p180 :003 > require 'active_record/acts/list'
=> nil
ruby-1.9.2-p180 :004 > ActiveRecord::Acts::List
=> ActiveRecord::Acts::List
