James, a complementary note: nut 2.4 (the version in Jaunty) has removed the compat. with UPSCONN (the client structure) to the profit of UPSCONN_t only.
thus you'll end up with an FTBTS. this is also fixed in 0.62-4 (not far from upload). also note that 0.63 is underway, but it's not worth an FFE imo. cheers, Arnaud
