    You’re almost certainly going to need MySQL installed to have the MySQL gem installed (even better is the mysql2 gem, which Rails also works with – just use mysql2 instead of mysql in your database.yml file).

    I find the best way to get MySQL on my Mac whenever I format it (which, admittedly, is rarely) is to use Homebrew. So, if you don’t have Homebrew installed, I’d start with that… and once that’s done, it should be a matter of running sudo brew install mysql, and running the instructions it provides after the installation is done.
