I built with OS X Homebrew (http://brew.sh) and it looks like their formulas use --enable-shared by default, although there is an option to turn it off (https://github.com/Homebrew/homebrew/blob/master/Library/Formula/llvm.rb). I was trying to work on a patch to update to 3.5.0 when I ran into the problem.

That would be nice but unfortunately there is not equivalent of
--enable-shared in the CMake build right now. You can build shared
libraries with CMake but it will build separate shared libraries (e.g.
libLLVMSuport.so, libLLVMJIT.so, ...) instead of a single monolithic
shared library (i.e. libLLVM.so) .

I've committed the fix to trunk in r217484. Could you try trunk? If it
works for you then I'll close PR20884
Thanks,
Dan.
