Globalize problem

Hello all.
I'm Ruby and Rails newbie.
I have the following error after installing the Globalize gem trying
to run script/server:

$ ./server
=> Booting WEBrick...
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/
dependencies.rb:376:in `new_constants_in': You have a nil object when
you didn't expect it! (NoMethodError)
You might have expected an instance of Array.
The error occurred while evaluating nil.empty? from /usr/lib/ruby/
