Literally none of my tekkit mods are loading on a Multiplay server

Title: Literally none of my tekkit mods are loading on a Multiplay server

Version: 1_0_3

OS: Macintosh OS X 10.8.3, though the server runs something else

Java Version: Java 6

Description of Problem:

I tried to make a Tekkit New server, and it worked for a time. But then the server started looking for 'tekkit.jar' and not finding it, so my server wouldn't start. So I renamed the existing jar file to tekkit.jar and it seemed to work. It became apparent that not a single Tekkit mod is actually loading to the server, despite the fact that the spawning bar shows the items. When one is clicked, it says no item of that id exists. Treecapitator is also down, which is another hint that stuff is up. This is not necessarily a Tekkit issue, but any guidance in fixing this would be adored, and Tekkit Discussion seemed like the wrong forum too.

Error Log:

No specific error, just isn't working

The Tekkit server ships with a file called tekkit.jar, so if you didn't have it, then you installed your server wrong.
