lua http installation failing with lua 5.3 #187

This is probably not a bug/ some mistake on my side, still reporting if someone can clarify
Steps :

1. Install lua 5.3 : apt-get install lua5.3

2. Install luarocks : apt-get install luarocks

3. Install lua-http FAILS

4. Install Lua 5.1

5. Install lua http SUCCEEDS though I get some WARNINGS
