mas currently requires the bundler RubyGem in order to bootstrap and build the project. There are a number ways to install bundler but if you have never used it before then installing it with gem should be enough.

$ gem install bundler

You can now bootstrap the project by executing the bootstrap script from the mas sources script directory:

$ script/bootstrap

You can now build from Xcode by opening mas-cli.xcodeproj, or from the Terminal:

$ script/build

Build output can be found in the build/ directory within the project.
