I appears the conda installation on Linux is not defining LD_LIBRARY_PATH so that the libpyferret library can be found.
I guess that means that it's a bug on the part of the pyferret installation. I mean, I thought
should set all necessary environment variables. Perhaps we need to set LD_LIBRARY_PATH in
/usr/local/miniconda3/envs/FERRET/etc/conda/activate.d/env_vars.sh ?
Cheers,
