Based on local testing of the buildbot binaries, everything looks good. Of note, buildbot binaries shouldn’t be used when compiling against the Xcode-provided compiler, since that can vary between the builtbot and users’ machines. (And that’s consistent with the behavior of mpich-* ports.) But most openmpi-* subports can utilize the buildbot binaries, eliminating local builds in many cases.
