[ncl-install] ncl installation

[Karin Meier-Fleischer]

Are you running MacOS? Then see 
https://www.ncl.ucar.edu/Download/macosx.shtml#InstallCompilers which 
says that you have to use the GNU 7.x compiler.

I recommend to use the conda or miniconda installation method 
(https://www.ncl.ucar.edu/Download/conda.shtml) which takes care on all 
dependencies and environment variables.
