Symbol not found with resty command on macOS

I built and installed last version (1.15.8.2) on macOS (10.14.6) but I cannot excute Getting started section of the guide. When I launch resty -e 'print("hello, world")' I obtain the following error:

nginx: [error] lua_load_resty_core failed to load the resty.core module from https://github.com/openresty/lua-resty-core; ensure you are using an OpenResty release from https://openresty.org/en/download.html (rc: 2, reason: ...io/Downloads/3scale/OpenResty/lualib/resty/core/time.lua:43: dlsym(RTLD_DEFAULT, ngx_http_lua_ffi_now): symbol not found)

Reproduce the resty -e 'print("hello, world")' command on macOS 10.14.6 using the reported OpenResty 1.15.8.2 setup. Start with the lua-resty-core load error and the referenced resty/core/time.lua and ngx/process.lua paths; done means the command runs without the reported missing-symbol errors.
