Project that builds won't archive. iOS

So, my unity project builds and runs on my test device nicely - however when I try to archive it, I get two CopyPngErrors and 69 linker errors. It's very frustrating, as I presumed a clean build would mean a clean archive. A pastebin of the error log is at http://pastebin.com/LHNcV0BD I'm using the latest version of xcode. Any help would be very much appreciated! EDIT: I do have distribution provisioning.
