I always wondered why pkg_pretend never caught on. I to can see the advantage of it over REQUIRED_USE; it would allow the package maintainer to give specific error messages about why use flag combinations are invalid for a package. Without really knowing what the opposing viewpoint is, I think pkg_pretend is the better way to go as well. William
