TauDEM is broken in all JH environments

From Dave Tarboton

Raza Ahmad, cc’d, is working with TauDEM on CUAHSI JupyterHub. He is working to text Sciunit reproducibility concepts. He recently pointed out to me that while TauDEM used to work on CJH, it is not working at present. I went in to verify this and testing with the resource
https://www.hydroshare.org/resource/21d79df568c54c92bb954c62a63fa550/
found that it failed with the error
PitRemove version 5.3.9
ERROR 1: PROJ: proj_as_wkt: SQLite error on SELECT name, ellipsoid_auth_name, ellipsoid_code, prime_meridian_auth_name, prime_meridian_code, area_of_use_auth_name, area_of_use_code, publication_date, deprecated FROM geodetic_datum WHERE auth_name = ? AND code = ?: no such column: area_of_use_auth_name

I also get a warning
/opt/conda/lib/python3.9/site-packages/geopandas/_compat.py:112: UserWarning: The Shapely GEOS version (3.10.3-CAPI-1.16.1) is incompatible with the GEOS version PyGEOS was compiled with (3.10.1-CAPI-1.16.0). Conversions between both will be slow.

I’ve narrowed the error down to the environment variable PROJ_LIB. This variable is set to the PROJ directory inside the anaconda environment (/opt/conda/share/proj). When I unset this variable, the TauDEM executables work fine. However this will then break the Python GDAL installation.
