I see the version you have is Minecraft Bukkit Dev. Pretty sure that is for people that are making mods for Bukkit. If I remember correctly you need to switch it to the latest Bukkit that doesn't say dev on it. Mods and plug ins won't work otherwise.
The latest would be CraftBukkit 1.4.5-R1.0
I can change it if you want.
