Also, recent versions of OS X ship with git in the command line tools, but it doesn't seem hg is in that package. Since one possible advantage of git would be to efficiently sync the ports tree using git, I think that gives git a clear advantage.

Sigh. The popularity of git has always surprised me since Mercurial
accomplishes the same thing and is much, much safer to use. 

I have been with many other teams that switched to git because of a few
(loud) proponents and never once was it worth the headache of git. As a
team, they have all suffered from someone tripping over one of
fast-forward merging, rebasing, or figuring out what 'git checkout'
really does.

Mercurial on the other hand guarantees safety of history rewriting
(through changeset evolution) and has the better scaling over git,
thanks to Facebook's contributions:

... but I digress. This has already turned into a git vs. hg flame war
and I did not want to go down that path.
