BTW, I've looked back at the original logs.  The issue is this:

single_terminate: reason[socket_get_remote_addr() failed]

The reason is that we require 'credentials passing' via the
getpeereid() call or SO_PEERCRED, a feature not in posix but available
one way or the other on multiple unix-like systems, which allows one
end of the pipe to know the UID and GID of the other end.  

We don't have an implementation of this for HP-UX, so the AD DC won't
run.

I'm sorry the build doesn't fail earlier for you.
