Ruby is preinstalled with Mac OS, you write your script in TextMate, press Apple+R and the results pop up in a seperate window. Very nice and fast.
There are also 'Bundles' for Ruby and Rails, which let you develope stuff very quickly. Code completion, easy switching between model, controller and template etc.

If you have Mac OS, you should try TextMate (http://macromates.com/).
