hmm. drb_clent.rb does not initialize DRb. 
but, I found minor bug in drb/drb.rb, without DRb.start_service. 

Please try either of the followings.

(a) initialize DRb, in drb_client.rb. (recommend)

| require 'drb'
| STDOUT.sync = true
| DRb.start_service
| 
| cliObj = DRbObject.new(nil,"druby://localhost:5555")
| 
| 5.times { |i| puts cliObj.time_now; sleep(2); }
| 
| cliObj.bye


(b) patch drb/drb.rb.
