Luarocks fails to install on macOS BigSur

Just tried out my config (which I recently added a rock to) on my work mac (running BigSur not sure if that matters) and found that although the same install process seems to happen to setup luarocks via packer, the install process appears to finish but I don't think luarocks is correctly installed since further calls to install try to install luarocks again. The rock I also specified (penlight) is also not installed.
