     The people in charge of OCaml (they're at the French research institute INRIA) have stopped making pre-built packages for Mac OS X. One option you have is to use their package for a slightly older version of OCaml, 4.01.1 from Sept. 2013. You can find that as a "Precompiled binary for Mac OS X" on [this page](http://ocaml.org/releases/4.01.0.html).

+    A second option is to install the OPAM package manager and use that to build and install the latest version of OCaml. Here's how to do that:
+
+    1.  Download [this file](https://raw.github.com/ocaml/opam/master/shell/opam_installer.sh) and note where it gets saved to.
+
+    2.  Open a terminal and type:
+        
+            sudo mkdir -p /usr/local/bin
+            sh /path/to/opam_installer.sh /usr/local/bin
+
+        Except replace `/path/to` with the real location, that you noted in step 1.

-    instructions. (Use the MacPorts version of OCaml, instead of installing

-    However, if you do have Xcode, and want to do without MacPorts, then
-    what you need to do is download Findlib from
