 > This <https://github.com/kencu/macports-
 ports/commit/b671ba1875a6e1f28c074407105aeca1bb9d5303> should fix this.
 Just have to test it out on a few more systems.
 In your [https://github.com/kencu/macports-
 ports/commit/b671ba1875a6e1f28c074407105aeca1bb9d5303 commit], may I
 humbly suggest that instead of testing OS version, we test Xcode
 version.[[BR]]
 Something like this: {{{${os.major} < 11}}}--->{{{[vercmp ${xcodeversion}
 4] < 0}}}.[[BR]]
 I am not 100% sure when xcrun started allowing absolute pathnames, but if
 it happened before Xcode 4.2.1, then {{{llvm-bin-sl}}} might not be needed
 even on Snow Leopard.
