The problem is that openmpi includes a libotf.so.0, but it's not in a
path that the system will usually look in for shared libraries, it's in
(libdir)/openmpi/lib/ . openmpi probably shouldn't have a private copy
of libotf in the first place (assuming that's what it is, and not just a
naming coincidence), but if it's going to have one, it should have a
line in the spec to prevent RPM auto-provides from giving the openmpi
package a Provides for libotf.so.0.
