So even if the fundamental mechanism is part of the base layer the error could still be determined in a PortGroup. And I think it'd make sense if the cxx11 portgroup raised the "don't build" signal if it detects a host that doesn't have libc++ installed.

I've explained the matter as best I can. You can refer to the mailing list archives for more details, specifically Clemens' explanation for why the matter must be handled by MacPorts base, not ports.
