Comment (by mojca):

 I need to check. Is this flag hardcoded in p5-wx sources? Are you using
 the default installation or the one with `libc++` default?

 I just need to add that while I agree with you, the port absolutely needs
 to be compiled with the same `cxx_stdlib` as wxWidgets and this often gets
 pretty tricky, there are still issues with some Python ports and upstream
 told me to specify the compiler with `CXX=/path/to/clang -stdlib=libc++`
 if I want the python modules to be compiled correctly on `libc++` setups
 on older machines. (The port should not hardcode the stdlib flag in any
 case though.)
