The directory structure all looks OK.  There would be an extra file in
/usr/local/netcdf/include/ and /usr/local/netcdf/lib/ if you had a C++
compiler and wanted the C++ interface, but what you have should work
fine for C and Fortran programs.

When you link a Fortran program with your installed library, you need to
tell the compiler where to look for the library, since it's not in any
standard place like /usr/lib/ or /usr/local/lib/.  So you need to use
something like 

   f77 -o program -I/usr/local/netcdf/include program.f -L/usr/local/netcdf/lib 
-lnetcdf

where "program.f" is the name of your Fortran source file and "program"
is where you want the executable.

If you don't have the -L/usr/local/netcdf/lib option to f77, it will
look in /usr/lib/ and use whatever netcdf library it finds there ...

Hope this helps.
