Hi CB, Very informative. Thanks a lot. I understand it and it makes sense. Interesting experience for a linux newbie. So in short, x11 I can safely forget about. Good to know. Thanks for trying it out by the way. I have xcode installed, because I want to use mac ports some day soon, but even getting an overview of what xcode all contains is as clear as mud to me at this time. Your clue pointed me to where I might find some of the files that xcode installed, to begin with, which will be interesting. The xcode installer app gave a whole bunch of stuff that I don't know how to find yet, but that's all a different matter. I now know a bit about x11.
