[Homebrew] brew upgrade Warning: No developer tools installed. -> Run `xcode-select --install`

Got a warning when running brew upgrade on Mac OS X Mavericks.

% brew upgrade
Warning: No developer tools installed.
You should install the Command Line Tools.
Run `xcode-select --install` to install them.

Apparently I should run xcode-select —install.

% xcode-select --install
xcode-select: note: install requested for command line developer tools

That’s all from the Gemba.
