Looks like a version conflict between your local LLVM sources and the LLVM
version this was written against. I would ask them to give you a specific
LLVM revision number, then you can check out that specific version.
Also, depending on what you need, LLVM now has a built-in PTX back-end.
It's not quite robust yet, but it is capable of compiling a wide range of
compute code.
