Ullr:anchor scott$ sudo xcodebuild -license
Password:
You have not agreed to the Xcode license agreements. You must agree to both license agreements below in order to use Xcode.
Hit the Enter key to view the license agreements at '/Applications/Xcode.app/Contents/Resources/English.lproj/License.rtf'
After hitting the space bar a bunch of times, just agree and you're back to work.
