The compiler warnings should be fixed... thank for the hint, Tim.

That's absolutely correct.
These four libraries specify the different parallelization types:

libvt: for serial applications which use neither MPI nor OpenMP
libvt.mpi: for MPI parallelized applications
libvt.omp: for OpenMP parallelized applications
libvt.ompi: for hybrid applications (MPI and OpenMP)
