Sorry that was indeed a wrong file. I attached the right one.
I *think* the problem comes from the this error:

Here, you are using the regular C++ compiler to link an MPI program, and
it forgets to link in one of the ancillary OpenMPI libraries that has
the opal_... functions. You ought to be using the mpic++ program to
compile. Do you have the CXX environment variable set?
There have been recent changes to the MPI cmake configuration. Are you
using the newest development version of deal.II?
Best
