I see that you're using a 32-bit lisp
#/setWantsLayer: is available on Mac OS X 10.5 and later. For
backward compatibility reasons, we supply Tiger-derived interface
databases with the 32-bit ports, and those interfaces (obviously)
don't contain the new-with-Leopard stuff.
I think it may be the case that Leopard-derived interfaces would still
work (for some value of work) on Tiger systems, and I think we'd like
to see Leopard interfaces for all Darwin ports in CCL 1.4.
(There's a ticket for this at http://trac.clozure.com/openmcl/ticket/481.)
Can you use the 64-bit lisp? It uses Leopard interfaces, so those
methods will be present.
If not, send me private mail, and I'll see about getting you Leopard
interfaces for Cocoa for x8632.
