New description:

 When I attempt to install the go port, the following dependency fails to
 build because it appears that macOS High Sierra has changed the location
 of the Clang runtime:

 {{{
 clang: error: no such file or directory: '/Applications/Xcode-
 beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/9.0.0/lib/darwin17.0.0/libclang_rt
 .builtins-x86_64.a'
 }}}

 Furthermore, I wasn't able to locate `libclang_rt.builtins-x86_64.a`
 within the following path for Xcode 9 Beta on macOS High Sierra:

 {{{
 /Applications/Xcode-
 beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/9.0.0/lib/darwin
 }}}
