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?
mpif90 -show
ifort -I/usr/local/include -I/usr/local/include -L/usr/local/lib
-L/usr/local/lib -lmpichf90 -lmpichf90 -lmpich -lopa -lpthread -lrt
and I've definitely compiled everything with the same compiler, as I've
made sure it's the only one I have compiled. Although I guess I didn't
try the "-DpgiFortran" option when compiling mpich2.
The -DpgiFortran looks odd to me but since I rarely build the netcdf4
fortran interfaces, maybe that's just the way to do it.
To be honest, I'm just following the advice of the ROMS guys, but the
make fails without it (although this is probably due to me compiling
HDF5 with that option too).
Any more ideas are welcome.
