Linker errors building on macOS Catalina #21

Hey there 👋 I’m exploring the Bazel+Haskell space, and in attempting to install hrepl (via bazel build //hrepl), I ran into the following:

ERROR: /private/var/tmp/_bazel_patrickt/9b0f64af68d3bba2996d9fad8a733686/external/rules_haskell/rule_info/BUILD.bazel:4:1: HaskellProtoc external/rules_haskell/rule_info/Proto/RuleInfo.hs failed (Aborted): protoc failed: error executing command bazel-out/host/bin/external/com_google_protobuf/protoc '--plugin=protoc-gen-haskell=bazel-out/host/bin/external/proto-lens-protoc/_install/bin/proto-lens-protoc' ...

It’s possible I’m missing something really obvious here, but if anyone has pointers as to how to fix this, I’d deeply appreciate it!

I'd suggest posting an issue to github.com/tweag/rules_haskell. The linking error doesn't sound like anything specific to what hrepl is doing, but maybe there's an edge case with haskell_proto_library?
