The current Makefile for devel/llvm doesn't allow you to use
REQUIRES_RTTI. It's a pretty common option, and is even enabled by
default in devel/llvm-devel. I emailed the maintainer months ago and
haven't had a response or seen any changes. I've never done anything
with ports before, but my best stab at it is below.

Thanks,
