I did and it runs at least more than the initial step. I am checking the output. 
Thanks.

Hello,
Please correct me if the way to disable scalar output for complex grid functions is e.g. deleting the lines WEYLSCAL4::Psi4r and WEYLSCAL4::Psi4i below. 
They are the only I recognize as complex numbers. Which information am I loosing so?

Those are real numbers - we don't use the complex data type in WeylScal4.  Maybe try disabling QuasiLocalMeasures?  We have had problems with MPI with that thorn before (https://trac.einsteintoolkit.org/ticket/495).

Some thorn requests a reduction for a complex datatype, which does not
work with this MPI version. This should be corrected in later versions
of Carpet. Alternatively, you can try e.g. disabling scalar output for
complex grid functions.
