Interesting.

I don't know why these lines are there, but it sure is funny.
In my view, these lines make no sense. All or almost all ports should
be able to be compiled with the default compiler, and the default compiler
should not be changed.

To make MacPorts be able to handle CC/CPP/CXX, some new variables like
configure.cc/cpp/cxx may be required. I think it might be too exaggerated.
Runtime version checking is the better solution.
