"Failed to build gfxboot theme" when creating customized iso

I get the dreaded "Failed to build gfxboot theme" error when trying to build usuing Ubuntu 12.10. I've checked and I do have both the gfxboot and gfxboot-dev packages installed. I also installed the gfxboot-theme-ubuntu package to see if it helped, and it didn't. Here's my build.log:
