--- Comment #21 from Alexandre Julliard julliard@winehq.org --- There is now a loader (and preloader) for every platform in the corresponding -unix directory. The main loader in /usr/bin/wine is just a small wrapper that launches an appropriate platform-specific loader.
But for the loaders to be able to find each other, they need to be installed in the same libdir.
