You're getting warning about C++11 features:


/opt/local/include/opencascade/Standard_Handle.hxx:75:19: warning: rvalue references are a C++11 extension [-Wc++11-extensions]
    handle (handle&& theHandle) : entity(theHandle.entity)

So:


* You're evidently using opencascade
* opencascade evidently requires C++11 mode or later
* You're evidently not using C++11 mode or later


To fix it add these lines:


# opencascade requires C++11 or later
compiler.cxx_standard 2011
configure.cxxflags-append -std=c++11


And you're getting these errors:


/opt/local/include/opencascade/BRepLib_MakeWire.hxx:176:81: error: a space is required between consecutive right angle brackets (use '> >')
                                 NCollection_List<NCollection_List<TopoDS_Vertex>>& theGrVL);
                                                                                ^~
                                                                                > >

                                                                              > >


If these problems persist after you're using C++11 mode, I guess the files mentioned will have to be changed in the ways indicated (in the opencascade port).
