binstubs option seems to be ignored

[dnagir]

It looks like the :binstubs => true option is ignored.

Here is the verbose output of guard:

> bin/guard -g features --verbose
Guard uses GNTP to send notifications.
Guard is now watching at '/Users/dnagir/proj/abc'
DEBUG (17:33:51): Hook :start_begin executed for Guard::Cucumber
Running all features

Disabling profiles...

And the config is:

guard 'cucumber', :binstubs => true, :cli => '--color --format pretty --no-profile '--tags @focus do
  watch(%r{^features/.+\.feature$})
  watch(%r{^features/support/.+$})          { 'features' }
  watch(%r{^features/step_definitions/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' }
end

Using the guard from master branch and guard-cucumber (0.7.4).

Am I doing something wrong?
