To be honest, I don't think this is the right approach to the problem. Truth is, dependencies in Gentoo are seriously broken, and most of the developers aren't even aware of that because of layers upon layers of hacks in Portage that make emerge somewhat go on. If you are really able to build something on top of the input you receive, it's probably going to be even worse than what's already in Portage. Example: many packages have impossible circular dependencies. However, Portage conditionally pretends they don't exist, preferring some random install-time breakage over fixing the packages in question. -- Best regards, Michał Górny
