I've installed RoR in my MacOS X using this guide http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
Here my versions:
$ ruby --version
ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]
$ rails --version
Rails 3.2.3
$ gem --version
1.8.23
I was unable to run my app so I've googled and modified Gemfile using this tutorial: http://ruby.railstutorial.org/ruby-on-rails-tutorial-book
Now this is my Gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.3'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
group :development do
gem 'sqlite3', '1.3.5'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.4'
gem 'coffee-rails', '3.2.2'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platform => :ruby
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.0'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'
When I run the app using
rails server
I got this:
=> Booting WEBrick
=> Rails 3.2.3 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

How can I solve the problem?
The error occurs because the new ruby has another syntax for hash. Tutorial that you used is outdated, I would suggest to try this: http://railsapps.github.com/installing-rails.html This is the best I could find. And also it is constantly updated.
In your case you need just to install new version of ruby and then reinstall rails.
