I understand that you are saying that, but I'm not convinced that's desirable behavior.

What criteria do you propose to use to exclude the dependency? The dependency is written "bin:xattr:xattr". Do you propose to exclude all bin (and lib?) dependencies? Or do you only propose to exclude bin (and lib?) dependencies that are already satisfied by the specified program (or library?)? And if so, do you exclude the dependency regardless of how the dependency was satisfied, or only if the dependency was satisfied by a file outside of MacPorts? And if the latter, where in MacPorts base should that determination be made? (As far as I know, MacPorts base doesn't currently care where the file that satisfies a bin (or lib) dependency is located.)
