The versions of Xcode and the command line tools on the buildbot builders do not get updated unless we ask the Mac OS Forge administrator to manually do so. I don't recall when that was last done. We could certainly do that to get any buildbot builders with outdated versions updated. Presumably it is wise to wait a little while after a new Xcode release, in case it turns out to be incompatible with something, as is often the case. But since 10.7 and 10.8 aren't receiving Xcode updates anymore we should update them to the latest available, which I guess is 4.6.3 and 5.1.1 respectively. I've filed a ticket:
