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.
