Ruby on Rails in OSX Tiger

At the moment I am learning Ruby on Rails (I must say it is very impressive). Unfortunately getting it setup in OSX Tiger was not as straightforward as one would hope.
Although Apple have included Ruby with Tiger there are a few things that do not work right.
For my own future reference (and for anyone else that is interested) this is how I got it working with MySQL correctly on OSX Tiger and MySQL's own OSX binaries.

Follow the install intructions found here:
Rolling with Ruby on Rails on Mac OS X Tiger

Once installed open a Terminal window and enter the following:

sudo sh
(enter the admin password)
curl -O; sh
gem install mysql -- --with-mysql-lib=/usr/local/lib/mysql --with-mysql-include=/usr/local/include

This should fix any Ruby issues and compile a fully functional Ruby MySQL driver ready for you to use.
