rspec-longrun is incompatible with RSpec 3.x

This just popped up for me when I updated rspec-longrun, which is being used by NMatrix:

Here is the relevant portion of my Gemfile.lock:

rspec (3.0.0)
  rspec-core (~> 3.0.0)
  rspec-expectations (~> 3.0.0)
  rspec-mocks (~> 3.0.0)
rspec-core (3.0.3)
  rspec-support (~> 3.0.0)
rspec-expectations (3.0.3)
  diff-lcs (>= 1.2.0, < 2.0)
  rspec-support (~> 3.0.0)
rspec-longrun (1.0.1)
  rspec-core (>= 2.10.0)
rspec-mocks (3.0.3)
  rspec-support (~> 3.0.0)
rspec-support (3.0.3)

Is there something we need to change in NMatrix to make this work again?

Update: It seems that the problem is with rspec-longrun using rspec 3.0. If I downgrade to the rspec-2.14.1, it works fine.

Yep, rspec-longrun is incompatible with RSpec 3.x at the moment. It appears they completely refactored the way formatters and colors work.

Hi,
FYI, we are affected by this on Debian, as we have transitioned systemwise to rspec3.

Perhaps too late for some, but I've (finally) updated "rspec-longrun" to work with RSpec 3.x.
