Okay, got it to work!

Three changes:

1. SqueakOSXAppDelegate.h - use NSObject instead ofNSApplicationDelegate

2. sqSqueakOSXScreenAndWindow.h - use NSObject instead of NSWindowDelegate

3. SqueakOSXAppDelegate.m - use CoreGraphics instead of OpenGL

//#ifndef USE_CORE_GRAPHICS
//#  import "sqSqueakOSXOpenGLView.h"
//#  define ContentViewClass sqSqueakOSXOpenGLView
//#else
#  import "sqSqueakOSXCGView.h"
#  define ContentViewClass sqSqueakOSXCGView
//#endif

Along the way, I found:

   Issue 5650: OneClick 1.4 can't be launched on MacOSX Mac Air 10.5.8
   http://code.google.com/p/pharo/issues/detail?id=5650

While I agree that support for old OS releases should have a reasonable 
limit, I don't buy 10.5 dropped when 10.8 is around the corner is the 
right limit. My machine is circa 2009, just three years or so. Apple may 
have good reason to want to move the user/developer base off of 10.5, 
because of hardware (pad/phone) and UI native widget changes. In the 
Squeak/Pharo case, we just need a single window to draw in - that should 
hardly obsolete a three year old computer.

I'll add this thread to the issue report (5650).
