openbabel2 uses archaic Apple wxWidgets and bleeding edge Eigen3, which fails

[barracuda156]

Not sure how this is supposed to work. The current Eigen3 requires C++14, 3.4.0 requires at least C++11, but the port picks gcc-4.2 and Apple wxWidgets from system prefix. While setting the C++ standard to satisfy Eigen is easy, that is not gonna work with wxWidgets, and I suspect not only Apple but also MacPorts' wxWidgets 2.8. The issue is that wxWidgets are very picky with regard to matching ABI, and apps built with a slightly newer versions of gcc that wxWidgets itself, for example, won't launch. This is why there are dedicated wxWidgets-cxx11 subports (i.e. even wxWidgets 3.0 built with gcc-4.2 cannot work with C++11 apps).

It probably should switch to wxWidgets-cxx11, and then use wxGTK for very old systems, and set the right C++ standard.
