Import LWJGL.jar error

I'm getting a new error:

I have imported the lwjgl.jar libary.

This is not a problem with Scala. lwjgl consists of a part written in Java and another part that is native. The native part should be found in form of a dll (Windows) or so (*nix) file. You should put this path in the java.library.path property.
