If USE=llvm is set, then media-libs/mesa pulls it in as a dependency. But if USE=-gallium, then the mesa ebuild ignores USE=llvm. From ebuild: use llvm && ewarn "Ignoring USE=llvm since USE does not contain gallium" So, it will be installed as a dependency but not actually used by the package at all. Reproducible: Always Steps to Reproduce: 1. set USE="llvm -gallium" 2. emerge -pv media-libs/mesa 3. See note presence of sys-devel/llvm in deps 4. emerge media-libs/mesa Actual Results: sys-devel/llvm to be installed as dep and During build receive warning message of: * Ignoring USE=llvm since USE does not contain gallium Expected Results: The package to only pull in the sys-devel/llvm when it is set to be used.
Good idea
