For each of the API server, Workbench, and SSO server (if we have it):

• Extend fpm-info.sh for the component so that the distro package declares its dependencies on other packages that our documentation tells you to install. This should include build tools necessary to build dependent gems, PostgreSQL (except for Workbench), and third-party tools called by the server (Git, Graphviz, etc.). When appropriate, the dependency should specify the minimum version required (e.g., API server requires git >= 1.7.10). This should not include Ruby, Ruby Gems, or Bundler, since we want to support RVM-based installations that won't install those via packages.
• After that change is merged, update the documentation to remove the separate installation of these dependencies.
