Yep, looks like Pat's cocked it up. X86_64 packages have ended up in the 32ibit tree's before, and I guess they will again. Just wait for him to sort it out. He's usually quite quick when these little oopses are pointed out.
BTW, The 64-current Changelog.txt also has an incomplete entry for the new make pkg (Seems to have the description line, but not the package name)
