Only id the netCDF library was guilt with the configure option --disable-shared.

When the default shared library is built and installed, it "knows" where to find
the HDF5 library and other libraries such as libz and libcurl that it was built 
with,
so to link with it, you only need to specify -lnetcdf (or -lnetcdff for the 
Fortran 
netCDF library).

Well nc-config still works ok if netCDF is built with --disable-netcdf4, but the
default is to built wth HDF5 and the netCDF-4 functionality it makes possible
by default, assuming the configure script finds the HDF5 library, as specified
with the CPPFLAGS and LDFLAGS environment variables passed to configure.
