Not yet. I've been trying for almost a week now. It's quite hard to
get it working on any system more than 3 years old (and I'm precisely
taking this effort because I want to substitute gcc with clang on all
my Macs, but, the weird thing is that it's only easy to do so for
systems for which Xcode already ships clang).

Anyway, today I arrived up to a 98% of the build, and seemed to be
successful, but, at that point, it entered the test-suite, and
reported that cmake 3.2 was a requisite (well... that would have been
nice to be reported when generating the Makefiles at the start of the
build rather than at the end). I updated my cmake to 3.5.1, but now...
I type make and... ooops... start again at 0% of the build...

I don't surrender, because I really want to have clang on all my Macs,
but a degree of patience is really mandatory.
