Why can't I `make-frame' with emacs 22.1 under Leopard?  The error  
must lie in `make-terminal-frame', which says:

error: "Not running on a Macintosh screen; cannot make a new Macintosh  
frame"

I'm running ordinary emacs 22.1 in Terminal -- the one that came  
installed with Leopard.  Never had this problem until I upgraded to  
Leopard.

I love your work.  Please advise.
