Sounds like a real simple s/OPAL/OMPI fix, so I'll give it a go tonight.
I think a patch was put back to v1.3 that wasn't quite right -- I see pml_ob1_recvreq.h:183 and 223 have OPAL_HAVE_THREAD_SUPPORT. But OPAL_HAVE_THREAD_SUPPORT isn't defined on the trunk -- only OMPI_HAVE_THREAD_SUPPORT is defined.
Can someone fix?
