Thanks! I just found out about missing via strace.

4996 execve("clang+", ["clang+", "/abyss/haohui/source.swift/Hello"..., "L", "/opt/swift-2.2-SNAPSHOT-2015-12"..., "L", "/opt/swift-2.2-SNAPSHOT-2015-12"..., "-Xlinker", "-rpath", "Xlinker", "/opt/swift-2.2-SNAPSHOT-2015-12"..., "-lswiftCore", "@/tmp/main.swift-a403cd.autolink", "-Xlinker", "T", "/opt/swift-2.2-SNAPSHOT-2015-12"..., "-o", ...], [/* 35 vars */] <unfinished ...>

Needs clang installed.

Note that we are considering adding a special case to the package manager to improve our diagnostics in this case, to make it more clear that this is just a case of missing "clang++". See:
apple/swift-package-manager#12

We have updated the getting started page to mention the clang requirement.

I have also added a warning on build failure should clang++ not be detected in `PATH`.
