That's not the same thing at all. Different versions, sources, etc. Should they really be he job of the OS package manager even when statically linked?

When statically linked it's even simpler: the dependency is used only during the build.

Maybe I wasn't clear, I'm advocating a solid build system and build dependency manager should be part of the core.
