I’ll add that when building OpenMPI 3.0.0 with an external PMIx, I found that the OpenMPI configure script only looks in “lib” for the the pmix library but the pmix configure/build uses “lib64” (as it should on a 64-bit system) so the configure script falls back to the internal PMIx. As Robert suggested, check your config.log for “not found” messages.
In my case, I simply added a “lib -> lib64” symlink in the PMIx installation directory rather than alter the configure script and that did the trick.
