[Tekkit server not loading correctly..]

It appears I have installed Tekkit correctly as I had it running locally before I uploaded it to my server host.. After I uploaded the files I keep getting these errors.

I am running Ubuntu 10.10 with the latest version of Java 1.7 on the machine. Here is the log:
