I\'m using Ruby on Rails (Edge, the development version), and Ruby rvm 1.9.2.

I know this thread already has a lot of answers but I'm going to throw in what worked best for me.
There is a gem called jquery-ui-themes that includes the default jQuery UI themes already converted to sass using the image-path helper. So you can include the gem and get any of the default themes out of the box just by adding them to your application.css file
If you want to use your own custom theme (as I did) there is a rake task that will automatically convert the CSS file to SCSS and use the image-path helper to find the right path.
