Thanks Stefan. I tried upgrading the Homebrew formula to 3.11.8 but I'm
still getting the test failures due to MPI_Init():
---
./run_unitTests
Running unitTests...
Testing AMPL Solver Executable...
---- 8< ---- Start of test program output ---- 8< ----
==> Warning: Treating 1 binary and 1 integer variables as continous.
*** The MPI_Comm_rank() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.
*** Your MPI job will now abort.
[Aragorn:91158] Local abort before MPI_INIT completed successfully; not
able to aggregate error messages, and not able to guarantee that all other
processes were killed!

I looked through the updated source code but it's not clear to me who's
supposed to set HAVE_MPI_INITIALIZED?
Thanks
Dominique
