The following patch should help:

# HG changeset patch
# User Maxim Dounin <mdounin@mdounin.ru>
# Date 1339809190 -14400
# Node ID 94e0eb86b0d0743f8ddbe946f142b35d6a606e2e

Fixed "sendmsg() failed" alerts on HP-UX.

HP-UX needs _HPUX_ALT_XOPEN_SOCKET_API to be defined to be able to
use various POSIX versions of networking functions. Notably sendmsg()
resulted in "sendmsg() failed (9: Bad file number)" alerts without it.

See xopen_networking(7) for more details.
