Dear Fernando, I would say adding a dependency on libc++ from ports is not necessary. On a standard system you can pass the compiler an option like -stdlib=3Dlibc++ a= nd it works. This library is usually linked against when compiling with c++11 or newer. Maybe adding the appropriate compiler option [1] would be a better choice?
