Mac OS with homebrew also has some problems. OpenMPI 1.8.5 was just released (6th May), and Homebrew is using it, since it is the latest version.  There is a problem with huge memory leaks in the orterun process:  (https://github.com/open-mpi/ompi/issues/579).  For the tests, this means that the memspeed test can take down the machine, and I assume trying to use cactus for anything serious will also not be possible.

I'm testing now to see if we can compile OpenMPI from the external library, and Barry is seeing if it's possible to ask for the previous version of OpenMPI from Homebrew, which he has verified doesn't have the problem.

MacPorts doesn't have this issue as it is using 1.7.5, which is well-established.
