 It's a comment that my experience with LLVM GCC is not good. I encounter
 failures where "normal" GCC just compiles. (Clang as well is a bit picky.)

 Anyway, when I asked whether it's possible to change the Portfile I
 intended to check whether other compilers work well when I invoke 'port
 build ...'. Or whether it works to compile a different variant of this
 package! During the compilation time I could google for the LLVM GCC
 error.
