[pyngl-talk] Fix for PyNGL conda installation errors

We’ve recently received numerous reports that our conda installation instructions <http://www.pyngl.ucar.edu/Download/> are resulting in an “UnsatisfiableError” when trying to install PyNGL.
The good news is that we've found a workaround for this issue:
conda create -n pyngl_fix -c conda-forge -c conda-forge/label/broken pyngl poppler=0.52 xerces-c=3.1 gsl
The (potentially) bad news is that this workaround requires a “broken” version of the GDAL/libgdal dependency to be installed alongside PyNGL, which may break compatibility with other conda packages. If no other conda packages are installed in the conda environment containing PyNGL (“pyngl_fix” in the example command above), then this should not be an issue.
If anyone tries this workaround and continues to experience problems installing or running PyNGL via conda, please let us know.
