Outdated
| compiler that prevents proper compilation of older hwloc packages | ||
| (1.11.6 and older) shipped with some Open MPI releases. This problem | ||
| can be avoided by using the GNU compiler to build Open MPI, or by | ||
| using an external hwloc (1.11.7 or newer). |

I don't think this is right (rhc would know for sure). I think 1.11.7 is broken as well when using Clang on FreeBSD 11.1.

Hmm... not sure where I got the idea concerning 1.11.7.

The clang 4.0 compiler that ships with FreeBSD 11.1 doesn't work well with OpenMPI. Workaround is to use a GNU compiler. Related to open-mpi#3992. [skip ci] Signed-off-by: Howard Pritchard <howardp@lanl.gov>
