I used your instructions at http://wiki.squeak.org/squeak/6177 and your emails reply to successfully build the Standard Interpreter running nativelly on 64 bit linux and powering a 64 bit image from the Jenkins server.
I collected 3 series of notes with the quick-n-dirty commands for 3 scenarios and posted them at my blog. If you think its worth linking to from the wiki or incorporating into the wiki, please feel free.
My attempt at building my own 64 bit image using SystemTracer semi-worked in that it created and image that booted but had no functionality to it. I am not worried about that at the moment.
Thank you for your help; its much appreciated.
Now that those exercises are over, I am turning my attention to debugging my build of the StackInterpreter using VMMaker.oscog and then to porting that to native 64.
