The problem is that zsh uses the curses API by default, so that
currently, the only way to use the ncurses library is to install
curses compatibility link (ncurses doesn't install them, but
Linux distributions and Mac OS X do). The problem occurs when
the user wants to install a newer version of ncurses (from
upstream) in /usr/local, /opt/local or whatever. As zsh uses
curses by default, it uses the old ncurses library (which, in
the case of Mac OS X, is buggy).

To be able to use ncurses by default, I had to change the configure
script:

-  termcap_curses_order="tinfo curses ncurses termcap"
+  termcap_curses_order="ncurses tinfo curses termcap"
