After reviewing: https://trac.macports.org/wiki/PortfileRecipes#compiler I tried:

    compiler.blacklist      *clang* *llvm-gcc-4.2
    compiler.whitelist      macports-gcc-4.9

    pre-build {
        build.args      CC=${configure.cc} \
            CXX=${configure.cxx}
    }

This builds with gcc 4.9 successfully.

Because the modified GCC has a problem with function overloading it is not suitable for the 2compilation of cgx.
