So this particular port comes up with this error probably because the deployment target is set to 10.6 in the xcode project. 

But there are _lots_ of ports that don’t build with the c++ stdlib specified in cxx_stdlib.

These are forced one way or the other in a way that works to fix a problem — eg. cmake and many others.

Also, on systems with libcxxonoldersystems, xcodebuild will not accept certain settings on certain systems, even if we know they could work with our newer compilers.

We might see quite a few errors with this, I suspect…
