I am actually pretty sad about this. Installers (deb, exe, etc) and libraries can sometimes be hard to build and require a difficult to setup environment. Its easy to sit there from a throne built on blog apps and twitter clones and say "they should make it better" but sometimes complex systems with large teams are difficult. Having them as your dependancies is made a little easier when you can just grab an installer that has been built with the proper version of -blank-esoteric-dependancy-or-build-tool-
