'uninitialized constant Dispatcher' when calling rake features

Hi,

I’m facing an issue with cucumber: when calling ‘rake features’ I get
an uninitialized constant Dispatcher (full stacktrace here:
http://pastie.org/297842).

I’m using Rails 2.0.5, the latest webrat/cucumber/rspec/rspec-rails.

Did anyone meet this issue ?

cheers,

Thibaut
