Likely the same base issue as #57358.

Comment (by jjstickel):

I can confirm the workaround in #57358#comment:11 worked for me. I
installed petsc with these variants:
{{{
port -u install petsc +gfortran -mpich +openmpi +sundials -accelerate
+openblas
}}}
where I already had openmpi-default +gcc8 installed.
