Mad props should be given to these guys for (IMHO) Doing It Right(tm). They're managing all their packages via ONE package interface (apt-get), and are able to reap the rewards of being able to more easily manage their knowledge, build tools, and build processes - at the end of the day, it's just simpler than having to go "Oh, this is installed via apt-get, these are installed via gem-install, over here these are installed via setup.py..." The whole gem/egg/cpan/whatever concept has serious issues when moving from the developer's laptop to the production environment, and I wish more folks took the time up front to do it natively, like Spotify and Hynek.
