it looks like you are using a C++ compiler to build C tests.  I'm a
little surprised that does not work, but we also never test things
that way.

While you need -DpgiFortran for serial netcdf, you don't need that for
parallel-netcdf

Since you specified --with-mpi, you do not need to specify all the
environment variables. No harm in doing both, but as you can see it
allows you to specify weird combinations.

Let me know if the suggestions above make these errors go away.
