Incompatible version?

Testing RSpec
1

I’m trying to use Rspe but I have this message error:

undefined method evaluate_value_proc' for classSpec::Matchers::Change’ (NameError)

I have this gems:

rspec 1.2.8, 1.1.12
rspec-rails 2.3.7.2, 2.2.12
cucumber 0.3.101, 0.3.100

Is there a incompatible version bettwen rspec and rspec-rails?
Thanks a lot.
