USE_EXPAND does something like: USERLAND="GNU" -> userland_GNU For Prefix, we just need the "prefix" USE-flag (not prefix_XXX), hence USE_EXPAND doesn't help us. Adding "prefix" to use.mask (and use.force in Prefix profiles) allows us to get the desired behaviour. -- Fabian Groffen Gentoo on a different level
