Please explain in more details why this is forbidden. man 5 ebuild contains nothing about this, I can't find anything in PMS also. If package manager misbehaves this doesn't automatically imply that ebuilds are broken (and not PM). > Consider it your priority to either replace the || () block with > a working solution (e.g. USE flags), or remove the := operator. What if package contains: || ( cat/foo:= cat/bar:= ) That is, it can work with either foo or bar, but needs to be rebuild on subslot changes. Are you suggesting to add USE flags for each alternative under each || () clause? This is ridiculous if foo and bar are drop-in replacements of one another. And dropping := will just break stuff if foo or bar contain more than single subslot. Best regards, Andrew Savchenko
