But I was wrong about whether "-m64" is needed.  It turns out that you
need CFLAGS=-m64 and FFLAGS=-m64 for gcc and gfortran if the hdf5
library you will link with was built with CFLAGS=-m64.

So the following worked for me woth netCDF-4.1.1 on a MacOS X 10.6.3
platform in that case:

  CC=gcc FC=gfortran CXX='' CFLAGS=-m64 FFLAGS=-m64 \
  ./configure --with-hdf5=$HDFDIR --with-zlib=/usr/lib
