Neither do I. It seems like an artificial simplification of skills that should be second nature to any half-assed Linux sysadmin. Dumbing down of complex topics to appeal to the common caveman.
Even ignoring package managers, if you know how to Google (please forgive the jewphemism) compiling 95% of packages is absolutely trivial. "Missing <something>.h!" -> search "something" -> install either "libsomething-dev" or "something-devel"
