Hi!
I have installed NBOpenGL from http://smalltalkhub.com/#!/~PharoExtras/NBOpenGL I have loaded Version 2.0 using the configuration
The method NBMacGlAPI>>glApiCall: fnSpec index: fnIndex attributes: attributes context: contextToRetry refers to the class NBCallFailureHandler, which is not existing
Apparently NBSTIvarLoader is also missing... I guess ConfigurationOfNBOpenGL is not loading everything... It would be nice to fix this.
Cheers, Alexandre
