[Pharo-project] more evidence that I am a newbie

I tried to load Andreas Raab's ffi-based OpenGL packages into Pharo 1.0... (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 I wasn't quite sure how to load them with Gofer so I did it manually with Monticello. However, when I "doIt" with 'OpenGL example' I get the error: MessageNotUnderstood: SystemDictionary>>platformName OpenGL class>>new OpenGL class>>newIn: OpenGL example No doubt its something totally trivial... Suggestions? Lawson
