It is correct for things at the top level of your drive ("/") to be owned by
root:wheel. Not sure why that wasn't the case for you before. I wasn't aware
that our installer would fix the ownership of items at the top level of your
drive. Maybe it's a feature of Apple's Installer.
You'll need to use "sudo" to have sufficient privileges to install ports, e.g.
"sudo port install mtr".
The error of mtr not being able to open a socket is probably a bug we've just
discovered in MacPorts today that affects only High Sierra:
https://trac.macports.org/ticket/54963
A new version of MacPorts to be released soon will fix it.
