Hi Zeng,

The last line of your debug message indicate that your are using the LDT shipped lua interpreter called JNLua instead of the one installed on your computer with lfs installed.

So you have two choices:
- Use the shipped JNLua interpreter configure it's LUA_PATH and LUA_CPATH environment variables to use the installed lfs libraries.
- Add the lua interpreter installed on your computer in LDT and use it to launch your scripts.

To do this, please refer to the LDT user guide Managing Interpreters part :
http://wiki.eclipse.org/Koneki/LDT/Developer_Area/User_Guides/User_Guide_0.9#Managing_Interpreters
See also the launch the Configuring debug sessions chapter:
