Yes!  This is the same message that a user reported when trying to run  
my Hoppi application [1] on Sierra.  It was built by me with CCL 1.10  
on El Capitan (I don't yet have Sierra).  The problem went away when I  
updated the application to build with CC 1.11 (see the thread "Tips on  
building a mac application" on this mailing list a few weeks ago).

The changes I had to make to get Hoppi to build with CCL 1.11 were:-

1. change my application class to subclass NS:NS-APPLICATION directly,  
instead of GUI::LISP-APPLICATION (which was removed in CCL 1.11), and

2. use GUI::*DELEGATE-CLASS-NAME* instead of GUI::*DEFAULT-NS- 
APPLICATION-PROXY-CLASS-NAME* to set the application delegate class  
for CCL::BUILD-APPLICATION.

Hope this helps,
Paul
