Ruby gem Error “Google is not a module/class”

[sagarjunnarkar]

When I first require 'roo' and then require 'google-search' I get an error

TypeError: Google is not a module

Again, I first require 'google-search' and then require 'roo' I get this error

TypeError: Google is not a class

See below for what actually happened on irb

The error is removed by modifying roo gem. https://github.com/sagarjunnarkar/roo
I don't know why, but after that I am getting segmentation fault error. So I think this is not solution.
