Anie, yes, that is some kind of installation problem. After this message,
let us move the conversation to the ncl-install mailing list, and drop
ncl-talk.
I am not experienced with conda installs or debugging. Given that, here
are some general suggestions that may or may not help. Perhaps someone
else has another suggestion,
* Contact conda support for advice. Probably try this first. Mention that
you now have two different errors: can not open libgsl, and contours not
showing. I think the first error is more important, and should be solved
first.
* Try uninstalling, then reinstalling GSL using conda.
* Uninstall, then reinstall NCL using conda.
* Deactivate your main conda environment. Then set up a new conda
environment in a different location on the same machine. Perform a fresh
install of NCL and all dependencies in the alternate conda environment.
* As a last resort, try an alternate installation method.
