[ncl-install] ncl not seeing NCARG_ROOT?

Are you using the ncl-ncarg package provided via apt on Ubuntu? I just tried running the same ‘load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"’ command on an Ubuntu 16.04 system using NCL 6.3.0 from the ncl-ncarg apt package and experienced the same error.
I was, however, able to successfully run the “load” command on the same machine using one of our precompiled binaries <http://ncl.ucar.edu/Download/> (specifically ncl_ncarg-6.4.0-Debian8.6_64bit_gnu492.tar.gz for Ubuntu 16.04).
I’m not sure why the ncl-ncarg package seems to be broken, but unfortunately we are not the maintainers of that package. If you continue to experience issues like this, I would strongly recommend using either a precompiled NCL binary <http://ncl.ucar.edu/Download/> or installing NCL via conda <http://ncl.ucar.edu/Download/conda.shtml>.
Additionally, the ncl-ncarg package provides NCL v6.3.0, which was released in March 2015. Both of the alternative installation methods I linked to currently offer NCL v6.4.0 (released February 2017) and will also offer NCL v6.5.0 for download when it is released in the near future.
I hope this helps!
