I think install rvm that will help you

  rvm get head && rvm reload
  rvm install 1.9.3
  rvm use 1.9.3@current --create --default 

The last line creates a gem set called current.

Now check to make sure you RubyGems was installed correctly by typing which gem in your terminal. Now update your gems.

gem update --system 1.8.24

Finally install rails.

gem install rails -v 3.2.3

I hope this works, let me know if you have any issues.
