No go at the moment - I am using my tiny macbook on holiday which is on too old a version of Xcode. When I try to upgrade it tells me I am out of space. I think rather than fight I will wait until I get back to a machine with more resources.

Hi Dominic,

You need to build/install LLVM with shared libraries.

Then, install llvm-general with -fshared-llvm (or, use my fork, which the stack.yaml files point to).
