At the moment Rust doesn't have a stable ABI (aside from things you mark as C-compatible), so dynamic libaries that stick around on your system to do things aren't used much. I bet there will be a solution for this once we stabilize the ABI, though I suspect it may already be solved (I think you can tell rust to dynamically link to the allocator too, or something).
