[ncl-install] gfortran library error

[Watkins, William]

Hi all,

Problem solved, I just needed the binary using the newer GNU compiler
(ncl_ncarg-6.4.0-MacOS_10.11_64bit_nodap_gnu610.tar.gz).  It might be nice
to update the "Choose and download the right NCL binary for your MacOSX
system" section with a "gcc --version" note or whatever is needed though,
so noobs like myself know which to download.

Cheers,
David
