[ncl-install] ncl-install Digest, Vol 144, Issue 1

[Andrei Kurbatov]

Jeff,
The easy fix is to install Anaconda 
https://www.anaconda.com/

and after that install ncl using conda 

http://www.ncl.ucar.edu/Download/conda.shtml

From a UNIX terminal window in sh/bash mode, type:

  conda create -n ncl_stable -c conda-forge ncl
  source activate ncl_stable
