def ruby_ok?
  ruby_installation_instructions_message =<<-RUBY_INSTALL_MESSAGE
  You can easily install ruby with 'rbenv' or 'rvm' utility programs.

  ----------------------------------
  We recommend to install ruby using the 'rbenv' and 'ruby-build' utility commands.
  On Mac OS X  to install 'rbenv' and 'ruby-build' using the Homebrew (http://mxcl.github.com/homebrew/) package manager do:
    $ brew update
    $ brew install rbenv
    $ brew install ruby-build

  To install ruby version 1.9.3-p194 do:
    $ rbenv install 1.9.3-p194

  To set the global version of Ruby to be used in all your shells do:
    $ rbenv global 1.9.3-p194

  To set ruby 1.9.3-p194 as a local per-project ruby version by writing the version name to an .rbenv-version file in the current directory do:

    $ rbenv local 1.9.3-p194

  To set ruby 1.9.3-p194 as the version to be used only in the current shell (sets the RBENV_VERSION environment variable in your shell) do:

    $ rbenv shell 1.9.3-p194

  ------------------------------- 
  If you prefer to use 'rvm' as your ruby management utility use the following command to install it for a single user:

  user$ curl -L get.rvm.io | bash -s stable 

  For multi-user installation and detailed rvm installation instructions check: https://rvm.io/rvm/install/    

  After 'rvm' has been installed run the following commands to install ruby 1.9.3-p194:
  rvm install 1.9.3-p194
  rvm use 1.9.3-p194
  RUBY_INSTALL_MESSAGE
