Presumably. Let’s find out for sure. What’s the output of:

port installed depends:webkit-gtk

Maybe webkit-gtk-2.0 is sufficient for those ports.

You cannot ignore these errors; you must resolve the problem.

A C++ runtime is a library that programs that were written in C++ use. libc++ is the default C++ runtime on Mavericks and later, and libstdc++ is the default on Mountain Lion and earlier.

Probably not.

Install MacPorts base from trunk and edit the relevant setting in macports.conf. I don’t recommend this.

You would have to uninstall and reinstall all ports, and hope that none of them use any of the operating system’s C++ libraries. I don’t recommend this.
