There was a problem with the kernel build. That will have to be fixed by the repo maintainer. All you can do is wait, but it should not be long. A message will be posted here or somewhere noticeable when it's fixed.
amd, broadcom, and ndiswrapper all have the same problem in that directory.
But hey, Banjer: If the kernel source installed OK, you might try AMD's installer again. Look in its info for something like "clean up" that you might have to do before re-running it.
