Struct and opcode updates. Apply with "patch -p1".
I'm investigating some potential issues, but they may be specific to my setup. Hopefully this patch will get most everyone up and running.
If you experience any issues with decode or zoning (or anything else, really), please post below. Otherwise, I'll update SVN and the tarball as soon as I'm satisfied what I'm seeing is specific to my setup and not something that's broken.
