Another Github alternative: http://phabricator.org/, better than GitLab, even.

The Omnibus packages allow you to quickly install GitLab without having to do a lot of setup. The installation from source is also official, see https://about.gitlab.com/installation/
Its understandable why you wanted to bundle everything, and I bet it makes installation much easier for beginners and/or lazy sysadmins.
That said, it would be even better if the installation worked with existing software instead of installing its own copy of everything. It seems like apt package dependencies would be more elegant than bundling everything together.
Its great to have the installation from source as a supported option. But lets be honest, that's a world of pain that's simply unnecessary for a standard deployment.
