Here's a perl approach:
which, unlike all the other versions, doesn't require the data be pre-sorted, by virtue of adding all the tuples to a hash. I don't even think that sort in the output loop is required, unless you want the groups output in alphabetic order.
IIRC, the awk will come out in order, given the hash.
