[ncl-install] Issue installing NCL from conda

Hi Fernando,

Given that “ncl -V” outputs “6.4.0” correctly, I think that NCL itself is working in your first environment. The ng4ex script requires C shell to be installed on your machine, and based on the “bad interpreter” error message, I suspect it is not installed. However, unless you need to compile NCAR Graphics programs, I would not worry about this; again, NCL itself appears to run as expected.

As for the missing “libopenblas.so.0” shared library issue, I was able to reproduce this on my machine for both Python 2 and Python 3 environments. I will look into why this dependency is not being installed automatically, but for now you can manually install openblas as needed once your environment is activated: “conda install -c conda-forge openblas”

However, problems appear for both tests now, obtaining for "ncl -V" (ncl: error while loading shared libraries: libopenblas.so.0: cannot open shared object file: No such file or directory) and for "ng4ex xy05n -clean -W png" (bash: /home/fernando/miniconda3/envs/ncl_stable/bin/ng4ex: /bin/csh: bad interpreter: No such file or directory).
