title: lua script and when executed via wrk the version is different
body: <p>I have a lua script test.lua
  which when executed <code>lua test.lua</code> it executes and provides me output as expected and it uses lua 5.3 when compiling</p>
  
  <p>But when i execute the same test.lua via wrk (http performance test benchmark  brew tool) , it reached to lua 5.1 (which I dont have in my system) rather than 5.3</p>
  
  <p>And there is no any wrk config which tries to reach to lua 5.1 . I am not sure why it behaves different and hits different version of lua </p>
  
  <p>An hint to this confusion will be appreciated. </p>
