[Backgroundrb-devel] Unexpected NameError when invoking task on worker

Hi, I''m brand new to BackgrounDRb and trying to figure out the setup.

I cloned the git repository today as listed on the BackgrounDRb website.

Starting out with a very basic worker, but BackgroundDRb is crashing
on a NameError. Any help to resolve this issue would be greatly
appreciated! Thank you in advance!!

I am also attaching a text file with the output below since it might
be easier to see it in that format.

config/backgroundrb.yml
:backgroundrb:
  :ip: 0.0.0.0
  :port: 11009
  :environment: development
  :log: foreground


lib/workers/basic_worker.rb
class BasicWorker < BackgrounDRb::MetaWorker
  set_worker_name :basic_worker
  def create(args = nil)
    # this method is called, when worker is loaded for the first time
  end

  def keep_count
      count = 1
  end
end


Then I am starting BackgrounDRb and using the console to invoke the
worker, but run into this problem, and not sure what is going on:

[d96440a6 at d96440a6 ~/testapp]$ script/backgroundrb start
