The Cocoa-based IDE requires Mac OS X 10.6 Snow Leopard or later;
the command-line lisp still works on 10.5.

This requirement is mentioned at
http://trac.clozure.com/ccl/wiki/ReleaseNotes/1.7, which is
linked from http://ccl.clozure.com/download.html.  That's
perhaps not the most prominent place, I admit.

You're in exactly the right place;  welcome.
