Right, then this installation does not contain the necessary library to JIT
compile the query.

Yes, it requires that you compile with --with-llvm.  If you don't have llvm in
the PATH you might need to set LLVM_CONFIG to point to your llvm-config binary.
With autotools that would be something like:

    ./configure <other params> --with-llvm LLVM_CONFIG=/path/to/llvm-config
