edit added gemfile:

well figured out few things according have tried.

1.install bundler global gemset. rvm gemset use global && gem install bundler

2.in case have homebrew installed: try brew install ruby

3.if above solutions don't work case not sourcing rvm correctly, because not in login shell, therefore run

source ~/.rvm/scripts/rvm

and can execute bundle install.

4.last thing using rvm , might case rvm not selected default run

rvm use 2.1.1 --default 

and run bundle install

5.also can try rvm head && rvm reload before installing bundler.

let me know if i'm missing something.
