Trying to execute LibcxxOnOlderSytems (2nd ed.)

[ftp83plus]

Hi there, 

I had a serious issue with the machine, and needed to reformat the whole machine.

One of my first step was of course to reinstall MacPorts and selfupdate it. I started from a clean machine. But now fails to build clang-3.4. There's a full pastebin fo the log there:

What is it, exactly?

Thanks all,
