I get a completely different set of errors related to things like the deletiong of native sh_binary in Bazel. The error reported here doesn't show up for me (or maybe my build couldn't even get that far). I'm also building on Linux, but a repo mapping error like what's reported here should be platform-agnostic...

I was eventually able to reproduce this after fixing a bunch of other errors. This should be fixed when #269 eventually lands.
