-Furthermore, you'll be in one of two subgroups:
-
-* You'll have Apple's Xcode and the independent MacPorts system
- installed. (Probably you don't. If you don't know what I'm talking about, you don't have these.)
-
- If you don't have these, but want to try this route, you can read about
- the MacPorts system at <http://www.macports.org/>.
- This automates the building of Unix-type software on your Mac; it
- makes it a lot easier to check for dependencies, use more-recent
- versions of things, and so on. (Though as it happens, MacPorts only has an older version of
- our chosen implementation of Scheme.)
-
- There are also other package management systems available for the Mac, notably Homebrew and Fink. I only know a little bit about them.
-
- Xcode is available at
- <http://developer.apple.com/technologies/tools/xcode.html>. Some
- versions of this have been available for free, though you do have to
- register with Apple as an "Apple Developer", which involves accepting a
- legal agreement with Apple. I have an older version of this installed.
- If you download a recent version, email me and let me know how the
- process works so I can tell others. There are instructions about how to
- get Xcode in the MacPorts installation guide.

- The latest version of Xcode to work with Leopard is 3.14; more
- recent versions (>= 3.2) require Snow Leopard. 3.2.6 is last version that can be downloaded for free by users of 10.6 / Snow Leopard. (But if they pay, they can use up to Xcode 4.2.)
- Xcode 4.1 was free to all users of 10.7 / Lion. Is Xcode 4.6.x still available for free? Are Xcode 5.x and/or 6.x available for free?

-* Or you won't have those installed. (**Most Mac users will be in this group.**)
- Then you'll need pre-packaged (and usually pretty GUI) installers for
- everything. These are great when they're available and kept up-to-date;
- however sometimes those conditions aren't met.
