Comment (by michaellass):

 The same is visible in dyne2meter's log file, so I guess we have the same
 issue here.

 I hacked the Portfile in a crude way to force use of clang:
 {{{

      system -W ${worksrcpath}/build "cmake -LA ."
      system -W ${worksrcpath}/build "cmake --build ."
  }
 }}}

 With this, wxMaxima builds and installs fine. But there must be a better
 solution. The question is: why does cmake choose a different compiler
 here? And GCC should probably be blacklisted.
