Hmmm...I'll ask the Mellanox folks to fix that, but it will have to be for 1.8.1 as we have to release 1.8.0 today for the upstream packagers. I expect 1.8.1 will go out in the next 1-2 months based on prior experience (we always get a bunch of corrections after initial stable release as more people pick those up).
