Rspec autotest error

Hi all,

I tried testing with Rspec for first time, following a tutorial.

"rspec spec/" works fine but when I try 'autotest' it gives me the
error message below. I also made a gist about it: https://gist.github.com/779265

It seems like a redgreen or ZenTest error. I'm using Ubuntu10, Rails3,
Ruby 1.9 and RVM. Any help is appriciated, thanks in advance,
gezope

What version for gem you installed for auto test?

Hello, thanks for reply.

autotest (4.4.6)
autotest-rails-pure (4.1.2)
redgreen (1.2.2)
ZenTest (4.4.2)
rspec (2.3.0)
rspec-core (2.3.1)
rspec-expectations (2.3.0)
rspec-mocks (2.3.0)
rspec-rails (2.3.0)

Thanks a lot!
