} Unfortunately this doesn't work well with your solution, ie.
} 
}     export TERMINFO=${${=:-$HOME/$^delegates/pkgs/xterm/lib/terminfo(/)}[2]}

You've got two problems.  One is that you're trying a file glob, which
isn't going to work in the same shell-word with TERMINFO= (unless you
resort to using `setopt globassign').  Two is that =:- is in the wrong
place.

For the second problem, you'd want

    $HOME/${^${=:-5.9 5.8.1 5.8 5.7 5.6}}/pkgs/xterm/lib/terminfo(/)

You can get around the glob problem by using $(print ...), but I don't
know why avoiding a temp parameter would be important enough to fork a
new process.

    export TERMINFO=${$(print \
    $HOME/${^${=:-5.9 5.8.1 5.8 5.7 5.6}}/pkgs/xterm/lib/terminfo(/))[1]}
