Issue with Download,Compiling

Hi I'm idrach55 and I'm having an issue with jME. I have jMe 2.0 downloaded successfully onto my Mac. It is already containing (what I think are) the necessary .jar files. I use Eclipse and have a new user library containing the .jar files, but it cannot find the source path for lwjgl.jar. My Eclipse freezes when I attempt to download svn. Is there anyway at all I can create the source path for lwjgl.jar without using svn, and if so how?

        Thanks, idrach55
