I'm running into the same problems (including the issue #39 )

Now I have this problem and I suspect that the libllama.so is not found where it is expected to be.
Did you manage to make it work?

Might be you used the wrong commit hash? I got the 0.0.8 working with a very specific build: https://github.com/ggerganov/llama.cpp/releases/tag/b4138 in the changelog is the commit hash 42ae10bbcd7b56f29a302c86796542a6dadf46c9 mentioned. I hope that will help you too
