If that is indeed the case, and if passing some subset of these options
results in deadlock, it's not exactly user-friendly.
Maybe --enable-mpi-thread-multiple is enough, in which case MacPorts is
doing something needlessly complicated and Pierre's link was a red
That is very likely, though on the other hand, Homebrew is doing something pretty straightforward. I just wanted a quick and easy fix back when I had the same hanging issue, but there should be a better explanation if --enable-mpi-thread-multiple is indeed enough.
It is enough - we set all required things internally
