I am trying to compile a thorn arrangement for the qc0-mclachlan.par parameter file, with the einsteintoolkit.th on a macbook pro 10.6.3 intel core i7. I have attached the configuration file I am using and the output of the compilation errors. The errors are of type: Undefined symbols: "_ompi_mpi_comm_null", referenced from: MPI::Cartcomm::Clone() const in libthorn_CarpetSlab.a(mapping.cc.o) etc.... "MPI::Win::Set_errhandler(MPI::Errhandler const&)", referenced from: vtable for MPI::Win in libthorn_CarpetSlab.a(mapping.cc.o)
ompi_mpi_comm_null is a symbol from openmpi. Your configuration includes MPICH however, but has openmpi commented out. I guess some files are still linked against openmpi. Please delete the whole configuration (under configs/) and start from scratch.
