I think you just need to add "-lnetcdf" after "-lnetcdff" to link the C
library after the separately compiled Fortran library.  Most
installations have both libraries combined in one, but evidently your
installation specified "--enable-separate-fortran" to the configure
script when the libraries were built, so you have to provide both
libraries in the right order when linking.
