Tekkit Modloader erro

[lesmiff]

I'm running my server on a debian box and i was getting an error which i've already posted here but got no reply, so i decided to delete everything but the .jar and run it. When running it i got a modloader error. Please help

Launcher/pack Version: Most Recent

Operating System: Debian x86_64

Version of Java: 1.7.0_0.4

Description of Problem: Launcher error

I'd venture a guess that you either haven't installed the Tekkit server files correctly or you are having permissions issues.
