 > If one can indeed use gcc 5/6/7 to build C++11 and keep it linked
 against the system libstdc++, we need to start discussing that on the
 mailing list. I seriously mean that because that would solve most of our
 problems.

 As you know from our previous posts
 <https://trac.macports.org/ticket/52468#comment:45> I've been doing this
 for months on 10.4 and 10.5 PPC with good success. Occasionally you need
 to build something with apple's compilers (due to complex ObjC or apple-
 specific flags), but usually things build and work well. A list of what I
 have currently installed on 10.4 PPC is here if you're curious
 <https://github.com/kencu/TigerPorts/blob/master/installed_Tiger_Ports_list.txt>.
 10.5 builds more, but I don't have that list up right now.

 I have llvm-3.7, libc++, libc++abi, libunwind, libmacho, ld64, and cctools
 installed and apparently working on 10.5 PPC. Just can't quite get
 clang-3.7 to build through to completion at present -- some kind of out-
 of-memory error in the final link...
