Glad to hear it!

That's a very old version of gcc. The latest stable version is gcc6; I recommend using that instead.

Ok, but you're not meant to have to do that manually. Use "sudo port select gcc" to do it for you.

They can also be found in MacPorts documentation, and probably on Apple's web site somewhere.

cctools-headers is obsolete. Uninstall it / remove it from the list of ports that you're instructing MacPorts to reinstall.
