Nothing really could require OpenMPI's libotf as things stand, because
of what I wrote above: nothing can find it unless it uses a custom
linker path. If OpenMPI actually wanted the library to be something
other packages can use, it should really install it in a shared path
(and, as we've already discussed, rename it). If we're just talking
about different OpenMPI packages, they can handle the intra-dependencies
manually, I'd say.
