Ok, I tried this:

all of your undefined references are fortran symbols with a trailing
underscore.  this is a common yet irritating problem with fortran
compilers.  Unfortunately the easiest way to fix this is to ensure
that you build netcdf4, mpich2, and HDF5 with the same fortran
compiler. 
If you do an 'mpif90 -show', do you see 'gfortran' or 'ifort' as the
compiler being used?

The -DpgiFortran looks odd to me but since I rarely build the netcdf4
fortran interfaces, maybe that's just the way to do it.

==rob
I have now recompiled everything again with the same flags and compiler, but the same problem remains. 

Can anybody think of something else that might be causing trouble here?

Thanks,
Carlos
