Turns out the previous x86_64 version wasn't very x86_64ish. I'm working to put out an update so that it's fixed, but I don't currently have an x86_64 box so that's slowing me down a little. Hopefully it'll be in the x86_64 dev tree in the next 24hours or so.
Should be there now. Please try the new set and see if you still have the same issue.
