gringo 4.4 does not compile: no usable C++ compiler found

[damien.pous@…]

:info:build Checking for re2c... yes
:info:build Checking whether the C++ compiler works... no
:info:build error: no usable C++ compiler found
:info:build Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_ma

:info:build Exit code: 1

Failing build log is attached. I am running Mac OS 10.6.8. Macports installed gringo without any problem on a more recent machine, but I think I did not have to compile it locally.

In the future, please Cc the port maintainers (port info --maintainers gringo), if any.

Comments in the portfile state that the port requires a compiler that supports C++11. The port should use the cxx11 1.0 portgroup to enforce this.

The port will need to be UsingTheRightCompiler for that enforcement to take effect. The port should also be using the right -arch flags and should get a universal variant if possible.
