Because you also need to reject some older Clang versions. Did you add the 
check for them too?

Please think of Clang on Linux and FreeBSD, plus the older XCode that we still 
support on OS X. This is LTS and the last version before we require C++11, so 
expect people will try to build it with older versions.

Why do we insist on testing for something that proxies the real need? We need 
X and we know that Y provides X, so we test for Y. Why can't we just test for
