I never said you need Xcode.

The easy way to install the last version of ruby is to compile and install from source. If I want to do that, I need make, gcc, etc... Actually, if I want to install that tools easily I need to install Apple developer tools... and now I have to paid for that.

Okay, I can download and install each software from the apple.com/opensource... put it is such a pain. I can download XCode 3.... but it is not the lastest nor the greatest. Okay, I can change my OS, but I love it. It is sad that I have to move from it.
