Please help, the installation guide asks me to contact a "local expert" but I've looked on my classifieds and there tragically is no LIGGGHTS expert in town. I'm trying to install and compile (make auto) LIGGGHTS on my MacOS 12.1 and receive this error -
sed: illegal option -- -
usage: sed script [-Ealnru] [-i extension] [file ...]
sed [-Ealnu] [-i extension] [-e script] ... [-f script_file] ... [file ...]

I have tried installing vtk several times to no avail. Every single thing I do results in an error. Please help me install this thing.
