 Obviously it's silly for a build system to define `CC` to be a C++
 compiler. The variable `CC` is for defining the C compiler. If one wants
 to use a C++ compiler, one should be using the variable `CXX`. The perl5
 portgroup can't possibly be expected to know that a build system is
 misusing the `CC` variable...

 At least one problem seems to be in
 build/Wx/build/MakeMaker/Any_wx_config.pm where it says:

 {{{
   $config{CC} = $ENV{CXX} || Alien::wxWidgets->compiler;
 }}}
