The current build system links the ARPACK library only for the serial
build, so yes, you would have to use the serial build.

I don't see any reasons why it should not work. I can compile 18.2 with
MPI and with DFTD3 without problems. In case, you did not sort it out
yet, can you give more details about your build failure?
