Comment:

 Looks like the culprit is r102108 and the other similar commits. The
 compiler_name_map isn't exactly meant to be a public API in the first
 place, which is why it's semi-hidden inside the portconfigure namespace,
 but the issue here is that there's no check for whether it actually
 contains a mapping for the current configure.compiler value. The server
 generating the indices runs Linux, so the Xcode compilers are not
 available. (This also means you can't rely on having configure.compiler
 set "correctly" at index time.)
