Do you reference the netCDF library when linking POM2K?  How do you
reference it?

Does the library contain the netCDF Fortran-77 interface
(the symbols should start with the prefix "nf_")?  If it does, then the
problem is probably an incompatibility between the POM2K compiler and
the C compiler used to build the netCDF Fortran-77 interface.  What 
compiler are you using for POM2K?  What C compiler did you use for the
netCDF library?

Did the netCDF build pass the "make test"?  Was the Fortran-77 interface
tested ("make test" in the "fortran" subdirectory)?
