It’s possible that this will change before OS X Lion ships, but it’s still a troubling prospect today.
Why is this a troubling prospect today? The Developer tools you need are on your install disk. You did buy the operating system right? Just install them. If you don't have the disc handy at least you have the option of downloading it for free.
You're arguing that spending AN HOUR of your time is offensive. Think of everything you DON'T have to do since it's built into OS X. If that doesn't convince you, then yeah, OS X isn't for YOU - not Developers.
