What test you are refering to ? config.log contains the test results of the features that configure is looking for. Failure of some thread test does not mean OpenMPI can't support threads. In fact, I was able to run a simple/correct MPI_THREAD_MULTIPLE program uses pthread with openmpi-1.2.3 and the program finishes normally on this multicore Ubuntu box.
