Aha, I found the problem, which appears to be peculiar to FreeBSD.

Most Unixes don't care about the sin_zero field in a struct sockaddr, but
FreeBSD apparently does.  This patch fixes the problem:

FreeBSD also has a sin_len field, which most other Unixes don't, so you would
need to do an #ifdef somewhere for that.  However, it seems to work without
setting sin_len, so it may not be necessary.
