Build fail

[LalaChen]

Hello , I try to build this project. But I encounter some problem. When I build this project, the error message is shown in my CMD windows. The message is :
Android NDK: jni/../../libs/scripting/lua/proj.android/Android.mk: Cannot find m
odule with tag 'scripting/lua/luajit' in import path
Android NDK: Are you sure your NDK_MODULE_PATH variable is properly defined ?

I only execute build_native.sh. What's more, I don't do anything.

Please tell me how to resolve this problem. Thanks.
