config.log says the reason is:

error: unrecognized command line option "-std=c++03"

Thank you. What will be a correct solution, blacklist compiler? We do not have 2003 cxx_standard, do we?

There's not much difference between the 2003 and 1998 versions of C++. Does it build if you change c++03 to c++98? If so, write a patch to do that.

It is actually the portfile which adds the flag:

configure.cxxflags-append   -std=c++03

Will try replacing it.

UPD. Yes, c++98 works perfectly fine.
