So if app A uses lib B directly which uses lib C directly, and lib C got updated, revdep-rebuild will discover if the new C is incompatible with the current B. Re-emerge B and it usually just manages to do the right thing. Weird issues often crop up when you have plug-in modules that are loaded dynamically at runtime. Revdep-rebuild can't find these as they don't show up in ldd, the app itself figures out what modules it wants to load then tries, so if something is broken there, well you find that out when you run the app. emerge -e world is the only way I know to to fix these things with any certainty. Binary distro by the way usually don't have this problem happen to them, because with those lib C doesn't suddenly get ripped out underneath B and replaced ;-) -- Alan McKinnon alan.mckin...@gmail.com
