Just a note that Ubuntu does not actually have the same version as
MacPorts. As your output shows:

MacPorts:
> smartctl 6.6 2017-11-05 r4594 [Darwin 17.6.0 x86_64] (local build)

Ubuntu:
> smartctl 6.6 2016-05-31 r4324 [x86_64-linux-4.15.0-20-generic] (local build)

MacPorts has the 6.6 release, corresponding to svn r4594. Ubuntu has an
svn snapshot from sometime after 6.5 but before 6.6, r4324. This is
confirmed by the listed Ubuntu package version:

<https://packages.ubuntu.com/bionic/smartmontools>
