I'm still actively working on improving Sage's build system to strongly prefer dependencies from the system wherever possible. The actual implementation of this is not hard at all in principle, but it's slow-going just because there is a lot of prerequisite plumbing work that is taking time to get reviewed, and working properly on all the supported platforms.
