Is this using a release or the development version?

This might be a missing -lpthread on the link line. MPI should detect

PTHREADS = yes

You either set MPI_DIR to the directory where MPI is installed, or you
don't - and let Cactus try to find something suitable or build one by
itself (which seemed to have happened for you).
