ArgumentError (wrong number of arguments (0 for 1))

I implemented a small devise app using devise_sms_activable. I am using Rails 3.2.9 and Devise 3.1.0.

Here is my GitHub Respository: http://goo.gl/xp7lO1

I went through follow steps:

Added Devise Gem
Devise:install and Generated Devise on User Model
Generated Devise views
Added Sms activable Gem
Generate sms activable
Migrated User model
Added Phone field in Registration new views
Added Phone in attr accessible in User Model

But, i am getting the following error: http://goo.gl/7URT0c

I will really appreciate if someone can help me solving this problem.

I was able to overcome this problem by properly Auto loading lib.

But now, i am stuck at undefined method fail! (NoMethodError)

I am getting undefined method or variable fail! (NoMethodError). How can i access fail! in my helper method? I tried a lot to debug but i was not able to find any logic related to fail! in Devise code.

I will really appreciated if someone can help me fixing this error wrt Devise 3.1.0.

Here is the helper file: http://paste.kde.org/p8fecf169/
