Make everyone on your team happy, and create a script/setup for your Rails apps that instantly sets it up for development. This is handy when you borked things up and just want to revert to a clean database with some seeds or fixtures. And it is great because everyone on your team knows how to instantly get up and running on a new machine.
Here is a sample of a script/setup task in one of your apps that both developers and designers work on. Just run script/setup from your product dir and everything goes awesome.
#!/bin/sh brew install sphinx --mysql rm -f log/* bundle install --without production bundle exec rake db:create bundle exec rake db:schema:load bundle exec rake db:fixtures:load bundle exec rake db:seed
