Comment:

 According to the [https://github.com/open-mpi/ompi/issues/4373 upstream
 bug report] the problem is specific to using any version of gcc to build
 openmpi on High Sierra. The problem was fixed in [https://github.com/open-
 mpi/ompi/pull/4374/files this upstream PR] by disabling syslog support on
 High Sierra. The PR was merged in October, there just hasn't been a new
 stable release of openmpi 3 since then. The most recent release candidates
 of 3.0.1 and 3.1.0 were posted 8 days ago. Hopefully the final versions
 will be released soon and the port can be updated then. Or we can add a
 patch of the PR to the port.
