Comment (by ballapete):

 Replying to [comment:1 kencu]:
 > this smells like one of those situations where it is missing a proper
 `-std=c++11` setting. `gcc` sets these defaults differently than clang, at
 present. Google is your friend here -- others may have solved this already
 for you. Or search for this string in Macports, as it has likely happened
 in other ports too.

 Sorry, I don't understand the mechanics, rules, or whatever behind this.
 So I cannot ask a worthwhile question.

 Same error as without. Could be it's not library but a language problem.

 No, I'm not mixing… I don't know what I am doing wrong, but the stuff I
 compile works. i take some care in not telling my executables – or
 compilers – stuff. I just presume that my compilers are clever enough to
 record inside the executables which shared or dynamic libraries from which
 places they should use in daily life. I really like that sensible
 software.
