That's IUSE, not USE. USE flags are not touched (at least on non-hardened systems), so the change is only picked up by emerge if you use the --new-use option. > It changes nothing for non hardened users but forces a > rebuild of the affected packages. If you're positively sure that a package's USE flags did not change since when it was last compiled, you can avoid recompiling by adding (or removing) the "hardened" flag in /var/db/pkg/<category>/<package>/IUSE. andrea
