A similar issue once arose on Debian as we built Open MPI with the IB libs
even though most people don't have suitable Inifiniband hardware. In our case
that lead to a noisy warning; upstream later suppressed the warning given
You could try to suppress the probe for IB which we did (in the older 1.2.*
series of OpenMPI) via
# Disable the use of InfiniBand
# btl = ^openib
btl = ^openib
