DL is deprecated, please use Fiddle

Can anyone provide any insight on this error in Ruby? I get it when I run bundle exec rails server from the cmd in windows.

Hi Paden. ' DL is deprecated, please use Fiddle ' is actually a warning. The warning message comes out when you require 'irb' ( because irb require 'readline' ) or anything else wants to require 'readline'. If you feel it's annoying, you can comment out it at C:\Ruby200\lib\ruby\2.0.0\dl.rb.
