Installing the Xcode Command Line Tools on OS X 10.11 "El Capitan"Edit
For some reason, Apple makes it ridiculously hard to discover the download for these tools, but it turns out that you can install them easily with:
$ xcode-select --install
Note: You may have to install Xcode from the Mac App Store first, in order to get the xcode-select
binary. (I don’t know for sure, because I had already installed Xcode before trying to get the Command Line Tools.)
