Snow Leopard installs Ruby on Rails (with MySQL)
I did a clean reinstall of OS X Snow Leopard so there is nothing on my system.
I've installed Xcode and I'm ready to install Rails.
However, my system is a MacBook (MacBook2,1) and it doesn't seem to support 64bit by default. Apple is going to add this later.
How can I install Rails? Am I going about this in the usual way?
How about MySQL, do I need a 64 bit binary?

You can install 64-bit packages. They will be able to access memory and all the benefits of working with 64 bits. The only thing that doesn't boot on 64-bit is the kernel, but at the moment that's not something to worry about.
Check out Hivelogic's guide for installing MySQL, Rails and Ruby on Snow Leopard:

In most cases (maybe always, I'm not sure) you can run binaries compiled for 32 bits even if your system is 64 bits. They just won't have the advantages of 64-bit (faster storage of large things or processing files).
If your macbook is the latest it has 64-bit support (Core 2 Duo processor), if it's an older version (Core Duo) it is 32 bit. You can determine your processor type by checking the About This Mac check box from the Apple menu.
