Bruno is right, you definitely don't want compile MPI yourself in a cluster. At the very top of the WiKi there is an example of how to configure Spack on a cluster with external MPI https://github.com/dealii/dealii/wiki/deal.II-in-Spack Probably you missed this.
I will edit the WiKi to stress this fact.
