Can't install via luarocks

It resolves all dependecies except luabitop:

lua-websockets$ sudo luarocks make rockspecs/lua-websockets-scm-1.rockspec

Missing dependencies for lua-websockets:
luabitop

The install is failing on Lua 5.3, because it is using luabitop which doesn't support Lua 5.3. I am on MacOS, so the following worked for me after a $ brew install [email protected] libev:

$ luarocks --lua-dir=/usr/local/opt/[email protected] make rockspecs/lua-websockets-scm-1.rockspec OPENSSL_DIR=/usr/local/opt/openssl
