Underlying problem: I never got around to implementing raw-dylib support when used in a
bincrate; it only works inlibcrates currently. However, that's clearly a case that is supposed to work, and it should be relatively easy to fix -- it's just a case of adding the necessary stuff to the code path used to build up the linker command line for bin crates.Add 93842
