This project uses soloist and librarian-chef to run a subset of the recipes in sprout's [cookbooks]((https://github.com/pivotal-sprout/sprout).
Fork it to customize its attributes in soloistrc and the list of recipes you'd like to use for your team. You may also want to add other cookbooks to its Cheffile, perhaps one of the many community cookbooks. By default it configures an OS X Mountain Lion workstation for Ruby development.
Finally, if you've never used Chef before - we highly recommend you buy & watch this excellent 17 minute screencast by Ryan Bates.
