Try finding out which datatype this is. I suspect this may be about a
complex number. If so, I don't know why this is suddenly an error --
as I mentioned before, the code to define the MPI datatype for a
Cactus complex number didn't substantially change in the past years.

The corresponding code is in dist.cc in the routine pseudoinit. Maybe
we should be using the Fortran complex datatype for this, but Fortran
support is not necessarily enabled in MPI (and we don't need it
otherwise). Maybe we also need to define our own MPI operators for
complex types.
