Maybe you can reopen the bug and assign it to someone who uses curses?
Reopened, but left unassigned. (SF bug #457633 right?)
I think the bug isn't OSX specific, I would be very surprised if other FreeBSD's at least don't have the same problem (why would Apple take FreeBSD but put an older version of curses in, after all).
Well, maybe Apple took a copy of FreeBSD several years ago...
