It's possible the nc-config you're using was for a different buid of netCDF
that didn't specify --disable-netcdf4, because you should not need -lhdf5_hl or 
-lhdf5 for a library without netCDF-4.  It might work fine if you just 
delete those.

Most of the other libraries are just needed for the OPeNDAP client support.
"-L/usr/local/gfortran/lib -lnetcdf".

the dynamically loaded libraries "know" what they depend on, so you don't
have to.  With a shared build, you might only need
