The various pins here are causing issues: avro-cpp was updated to a new version that doesn’t work with LLVM 13, but nanodbc is broken with new LLVMs due to an upstream issue; LLVM 16 manages to hit the Goldilocks zone, but then the irods build fails because its overridden old spdlog’s API isn’t right somehow (perhaps related to my de2b823?). Not sure if there is a good solution here; ideally we would patch irods for newer versions of stuff rather than having to get into the weeds of maintaining a forked ecosystem with pinned old versions of everything that inevitably conflict with other updates.
