Your netCDF archive appears to be missing the object module
"fort-v2compat.o", which implements the Fortran-77 API and contains the
"ncopn" routine, -- among other things. Source-code for this module is
in the "fortran/" subdirectory.

In order to discover why your netCDF archive doesn't contain the
"fort-v2compat.o" module, would you please send me the file "make.log",
which is described near the end of the file "INSTALL.HTML".
