symbol not found in flat namespace (_luaL_loadbuffer) on mac with m1

Howdy. Got an issue with lupa not finding a symbol. Hoping to get some help on how to resolve this.

Stacktrace:

../../../Library/Caches/pypoetry/virtualenvs/workstuff-IU-yuaqp-py3.9/lib/python3.9/site-packages/lupa/__init__.py:32: ImportError

The code in question that is causing the issue is using python-redis-lock in a test case using fakeredis with a lupa extra.

Running python 3.9.9, lupa 1.13

thanks
