Is there some documentation that both me & google are missing somewhere? I'm trying to read between the lines of the scenario that's broken, with nothing but a log (that refers to a bunch of pretty important configuration files from somewhere I can't find) with a repo configuration that, again, I can't figure out. You say that we can't "build against LLMV as a dylib". Is this trying to build LLDB stand-alone, without a full LLVM repo around it? I'm also assuming you're actually talking about an SO and not a dylib, since the build is on Linux, not macOS. I really want to help, but I'm recently new to this space, so I'm missing a bunch of tribal knowledge.

Alternatively, if you have a repro, and can fix it by adding LLVMDebuginfod to libLLVM, that seems reasonable to me, given the design of LLVMDebuginfod (small, falls back to no functionality without libcurl, etc...) I've burned all day today trying to get a build & repro going, and have failed (my build is quite complicated). I'll try this on a personal machine tomorrow which should be simpler (though a couple orders of magnitude slower) than my work behemoth...
