I am trying to add forestry 1.4.6.2_bc2.2 to my tekkit server and I am having problems. I read around on the forums and tried adding z before the .jar file to make it load before ic2 but when I run the server i get this error http://pastebin.com/JqQu5rWQ . I can't figure out what the problem is from this. I added the client file of the same version to my technic launcher and that seems to be working fine. Also, I am using a mac if that matters.
