StepMania Scripts For OS X
This script can be used to bundle a .dmg installer of StepMania. It assumes you have already built a StepMania.app using Xcode and that your stepmania directory structure is intact as you cloned it.
To use this script, open a terminal and cd to your stepmania directory, then run the following commands:
cd Xcode/scripts
ruby mkrelease.rb
You'll see output as each stepmania sub-directory is copied into a tmp directory. If all goes well, you'll be notified that the dmg was created in your stepmania directory.
