​You need to specify the appropriate variant for the netcdf-fortran package
on a Mac to make sure it is built with the desired compiler.

For instance, if you use gfortran 4.9, then you will need to do something
like this:

sudo port install netcdf
sudo port install netcdf-fortran +gcc49

(you can change +gcc49 to be whatever MacPorts gfortran compiler you plan
to use). You can also do +gcc49 on the netcdf install, but that's not as
necessary since no F90 module is being built.

All the best,
