Can you check if your LD_LIBRARY_PATH environment variable is set to anything? If it is, try prepending $HFS/dsolib to it. In bash, it'd be something like: export LD_LIBRARY_PATH=“/opt/hfs13.0.198.21/dsolib:$LD_LIBRARY_PATH”
Houdini 13.0.228 should have this fixed behind the scenes without the user needing to munge their LD_LIBRARY_PATH. Can you try with that version without changing LD_LIBRARY_PATH?
