Configure should be using $MPICC to test for that library, not gcc (as
you can see, the compile line didn't bring in any additional necessry
libaries).

You should probably be configuring pnetcdf with the --with-mpi= flag.
For example, I have openmpi installed in
${HOME}/work/soft/openmpi-SVN, so I'd invoke configure with
--with-mpi=${HOME}/work/soft/openmpi-SVN
