I've seen the (original) project, another nice project is there in
this forked repository.

It is nice and would be nice to provide that functionality in MacPorts
(or even better: upstream).

But I don't see how that would solve any of the problems. The problem
that this addresses is already solved with the muniversal PortGroup
and has never really been an issue.

PS: Unless this also provides support for "-arch ppc". But even then
... cross-compiling C++11 sources on 10.6 for 10.5/PPC in a way that
will link to system stdlib? Nah, next year I'll drop the upstream ppc
binaries and advice users to install the same software via MacPorts
which will have perfect C++11 support via gcc-7 by then :) :) :).
