-- Add export LUA_INCLUDE="$(pkg-config --cflags-only-I luajit)"
+- Add export LUA_INCLUDE="-I/usr/include/luajit-5_1-2.1"
   so that we are finally building with LuaJIT headers.
   * I don't know why the configure file does not detect them by default
     are they placed in a non-standard location?
