I'm pretty new to squeak, please let me know if I should be looking
for help elsewhere, (and where that would be :) TIA

I'm trying to follow a OpenGL tutorial posted on YouTube by user
sparaig.  It's only 9 lines of code

(Installer repository: 'http://source.squeak.org/FFI')
	install: 'FFI-Pools';
	install: 'FFI-Kernel';
	install: 'FFI-Tests'.
	
(Installer repository: 'http://www.squeaksource.com/CroquetGL')
	install: '3DTransform';
	install: 'OpenGL-Pools';
	install: 'OpenGL-Core'.
	
OpenGL example  "this is where the trouble begins"

The transcript shows:

and here's the output I get in the debugger
