I'm not sure if the framework number is the same as the OpenGL version
number.  However I think ldglite prints the opengl version number when
run from a command prompt so you could check it that way.  Maybe it only
installs the new OpenGL if you have specific graphics hardware.

Then I'm confused as to what exactly is the problem with the GLUT
framework in the 10.2.3 update if the keyboard still works.

Yes, exactly.  It should not even open up a window.  So you're not
limited to the size (or for that matter, the availability) of the
screen.  Believe it or not, this does have it's uses.
