Right. apt-get install llvm-dev (or llvm-3.9-dev or such if you want to
install a specific version), does the trick here.
It's a bit easier to develop with a hand compiled version, because then
LLVM adds a bootloads of asserts to its IR builder, which catches a fair
amount of mistakes. Nothing you'd run in production though (just like
you don't use a cassert build...).

I don't think that's feasible at all unfortunately - the compiler IR
(which then is JITed by LLVM) is generated via another C API. We could
rebuild that one, but that'd be a lot of work.
