Just a note that Ubuntu does not actually have the same version as<br class="">
MacPorts. As your output shows:<br class="">
<br class="">
MacPorts:<br class="">
> smartctl 6.6 2017-11-05 r4594 [Darwin 17.6.0 x86_64] (local build)<br class="">
<br class="">
Ubuntu:<br class="">
> smartctl 6.6 2016-05-31 r4324 [x86_64-linux-4.15.0-20-generic] (local build)<br class="">
<br class="">
MacPorts has the 6.6 release, corresponding to svn r4594. Ubuntu has an<br class="">
svn snapshot from sometime after 6.5 but before 6.6, r4324. This is<br class="">
confirmed by the listed Ubuntu package version:<br class="">
