-     On Mac OS 10.7 (Lion) and later, the easiest way to get this library is to install
-     Xcode 4.2 or later.  However if you want to install tip-of-trunk from here
-     (getting the bleeding edge), read on.  However, be warned that Mac OS
-     10.7 will not boot without a valid copy of <code>libc++.1.dylib</code> in
-     <code>/usr/lib</code>.
+    Note that for an in-tree build, you should checkout out libcxx to
+    llvm/projects.

How much work is it to not require people to change lit.site.cfg? The `ln -s` is a bit gnarly, it'd be nice if it wouldn't have to be in the docs.
