now that is strange. Are you sure you pick up the same boost?
Could you post the original error from CMake error logs that shows how 
serialization test fails?

With HPC I used to have access to they did not use slurm, so I can't really 
comment here.
If that's during running quick tests or so, it could be related to a wrong 
MPIEXEC pickedup by deal.II config.
I wanted to fix that in Spack https://github.com/spack/spack/pull/11142 
but apparently this solution may not be fully functional for Slurm.

Denis.
