You can also encounter the same error message if you've downloaded XCode Tools but haven't yet agreed to the license.

From Terminal, run:

sudo xcodebuild -license

Enter your admin password, space through the agreement and type agree to accept. Run brew doctor and if necessary, brew update and you should be in good shape.
