The short answer was given on zsh-users a few weeks ago:

The long answer is that we need to change configure to detect this.
Here's a potential patch (against current 4.1.x from CVS, but I think
it'll apply to 4.0.4). I don't have access to HP-UX 11 to test it,
but it works for the "normal" tgetent() on my RedHat Linux box.
