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?
Select a #platformname selector with mouse , and then press alt-m to
see who implements that message.
Then try sending it from workspace until to make sure you found right
implementor.
Then modify the source code in OpenGL class>>new accordingly.

Unfortunately lots of nested references to it, starting with Smalltalk 
platformName.

I can get as far as changing it to SmalltalkImage current platformName 
but things get strange after that...

new
    Smalltalk platformName = 'Win32' ifTrue:[^OGLWin32 basicNew initialize].
    Smalltalk platformName = 'unix'
        ifTrue:
            [(Smalltalk windowSystemName = 'Quartz')
                "implicitly big endian"
                ifTrue: [^OGLUnixQuartz basicNew initialize].
                "default to X11 window system"
                Smalltalk isLittleEndian
                    ifTrue: [^OGLUnixX11LE basicNew initialize]
                    ifFalse: [^OGLUnixX11BE basicNew initialize]].
    Smalltalk platformName = 'Mac OS' ifTrue:[
        Smalltalk osVersion asNumber < 1000
            ifTrue: [^OGLMacOS9 basicNew initialize]
            ifFalse:[^OGLMacOSX basicNew initialize].
    ].
