For those who don't want to parse the test log to see the failures. There are 35 or so, focused in three categories:

• the InSitu engine File BPStepsInSituLocalArray.EveryOtherStep.Schedule0.Oddity1BP4.MPI.bp was found with an index file but md.0 has not contained enough data within the specified timeout of 10.000000 seconds. index size = 256 metadata size = 0 expected size = 2571.
• the Python bindings /disk-samsung/freebsd-ports/misc/adios2/work/ADIOS2-2.8.2/testing/adios2/bindings/python/TestNullEngine.py:36: RuntimeWarning: mpi4py.MPI.Datatype size changed, may indicate binary incompatibility. Expected 32 from C header, got 40 from PyObject
• installation tests ld-elf.so.1: Shared object "libadios2_core_mpi.so.2" not found, required by "libadios2_c_mpi.so.2"

I don't have a first guess as to what might be going on, but at first blush I wouldn't think that we're looking at an ADIOS-internal root cause, but instead a system problem or incompatibility.
