Could not find ZenTest-4.6.0 in any of the sources

Question

I get Could not find ZenTest-4.6.0 in any of the sources

When i'm trying to migrate my database using bundle exec rake db:migrate

$ bundle show ZenTest
c:/Ruby192/lib/ruby/gems/1.9.1/gems/ZenTest-4.6.0

$ rails -v
Rails 3.0.9
$ ruby -v
ruby 1.8.7

I have gem 'ZenTest' in my gemfile

What could be the problem?
