The HTML5ness of that CI result interface is making it impossible for me to determine whether it is building the python extension and if so to determine whether it has the same problem I'm seeing. The find function on that page isn't working right for me, and I can't see any way to download or copy the entire build log so that I can examine it in my editor.
