Yes, I had only one MPI installed at the time, and I did ldd
every which way.

There are more details in bugzilla :

  https://bugzilla.redhat.com/show_bug.cgi?id=986409

and in the openmpi users list :

  http://www.open-mpi.org/community/lists/users/2013/07/22346.php

but basically on my home workstation openmpi does not get along
with the hwloc to which it is linked in Fedora 18.
