It looks as if the netCDF-C library you are linking to doesn't support
netCDF-4, so the Fortran netCDF-4 tests are failing.

If it was your intention to not support accessing netCDF-4 files through
the Fortran interface, then I think you need to specify the configure option
--disable-netcdf-4 when you run configure to build the Makefiles.

If you actually intended to support netCDF-4, it may be that you are
unintentionally linking to a netCDF-3 only library that is still installed
in a lib/ directory searched by default.  You can determine where the
netCDF-C library is being linked from by using the "ldd" command on your
netCDF-Fortran library, even before it's installed.

It seems that the configure system should determine whether netCDF-4 is
desired and not set up to run tests of netCDF-4 functions if they aren't
available, so that may be a bug in our configure script.  If that's the
case, I'd recommend using the more recent v4.4.0-rc1: Release Candidate 1 
for netCDF-Fortran 4.4.0 available from GitHub, or the even more recent
netCDF-Fortran GitHub developer snapshot.
