Answer 1

Why did you run gem install json at all? Bundler takes care of that for you and will ensure that the correct version of each gem is installed (since sometimes dependencies require an older version). Run

gem uninstall json
bundle install

Also ensure you have source 'https://rubygems.org' at the top of your Gemfile.

As for the permissions info, you may have to run gem and bundle commands with sudo.

By the way, I highly recommend taking a look at and using RVM, particularly the gemsets feature. It will make your life infinitely better when developing Ruby apps. If you decide to do so, I'd also suggest trashing all the gems you've install using the system Ruby by running sudo rm -rf /Library/Ruby/Gems/1.8/. It's also important that when using RVM you don't have to use sudo when running gem (or bundle), which is not only safer but less typing too.
