Joe random student (actually named Jim) obviously doesn't have his install DVD anymore. He bought his laptop 2 years ago and is sitting in my office. Plus that XCode will be out of date, right -- full of bugs. > As a second possibility, one can sign up for a free account to the > Apple Development network (ADC) --- note that this has nothing to do > with the Apple App Store or your Apple ID.

This particular student (Jim again) couldn't get his apple id to work. Apple said it was "compromised" and he was fighting with their system to re-enable it. I guess he could get a new apple id though. > If you don't need the standard Unix development tools coming with > XCode (such as "make", "autoconf", etc.), but "only" need some gcc, But that's exactly what we need, right?
