[ncl-install] dyld: Library not loaded: /usr/local/lib/libgfortran.4.dylib

[Tao Zhang]

Hi,

I have used the second method "Installing NCL from a precompiled binary" 
to install NCL-6.6.2 in

my Macbook pro Majave (10.14.6).

  When I run the ncl command, I get the error "dyld: Library not loaded: 
/usr/local/lib/libgfortran.4.dylib". see below.

There is no "libgfortran.4.dylib" in /usr/local/lib/, but there is 
"libgfortran.5.dylib" in /usr/local/gfortran/lib, see below.

I have installed successfully gfortran 8.2 and it works well in my 
Macbook pro.

  So I am not sure what's the problem and how to fix it?

Thanks

  Tao
