Hi Vamsi - I'm glad that fixed the issue for you. The crash happens because the OOT is being linked to a specific ABI (e.g., MacPorts Python library), while the runtime is trying to use a different API (system Python library). The libraries' ABIs are different enough to confuse Apple's dynamic library loader (DYLD), and Apple's DYLD also isn't smart enough to work through the differences. I think the Python library APIs are the same. A possible solution to this overall issue is to not specifically link OOTs with a Python library, and instead force Python symbols to be loaded at runtime from whatever Python library is chosen. This solution has been claimed to work from HomeBrew users; I've tried to use their patches and failed when using MacPorts, which is why these changes are not in place. I hope this is useful! - MLD
