Here is the one from my macports.

~$ realpath --version
realpath (GNU coreutils) 8.17

It is sad to know that ubuntu doesn't have the latest version. It
seems that ubuntu is completely left behind in terms of keeping
packages up-to-date. At least for coreutils, macports (on mac) is
doing a better job.

I'd hope whoever maintain the package update see if they can learn
from macports to improve the package updateness (not sure if any
package maintainers will read my post).
