This is due to a less than brilliant py3k change:
    map(None, x, y)
doesn't work anymore and the recommended spelling is now this (??):
    list(map(lambda *a: a, zip(*itertools.zip_longest(x, y))))

The weave error that Scott reported on 3.x should probably simply be marked
as knownfail in master and 0.11.x.
