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

[Dave Allured - NOAA Affiliate]

Tao, the problem is that you need an older version of the gfortran runtime
library.  NCL's precompiled binaries were made for gfortran 7, not gfortran
8.  You could try installing gfortran 7 and see if that fixes the NCL
binary version that you have.

The NCL website currently recommends the conda method for installing NCL.
Please try that method if you need to.  You can also install NCL from
Macports, using the port name "ncarg".  Both of these methods require some
extra work.
