Understood. I thought that was the whole point of multilib though; to maintain compatibility with 32-bit applications by installing what ever is needed to lib32 directories. With jack mixed mode it's supposed to install a library in /usr/lib32 and /usr/lib64, the jack ebuild in pro-audio however fails the portage FEATURES=multilib-strict check, so either the pro-audio ebuild or portage is getting things wrong. I've been hesitant to touch jack as so many things depend on it and I don't want to go breaking a ton of things for people if the jack ebuild works for them. However, if you want to, please look at the ebuild I've been using in my overlay for the 1.9.* series for quite a while. The USE flags are very different to that of pro-audio ebuild but IMHO more easier to read, plus it allows jack-dbus and the classic jackd to be installed simultaneously. Best Regards Gav
