Doesn't install with rocksdb 7.0.2

I'm installing rocksdb-dev from alpine testing/edge. They recently updated it to 7.0.2 https://pkgs.alpinelinux.org/packages?name=rocksdb-dev&branch=edge ... but rocksdb-ruby doesn't compile with that:

From our Dockerfile:

RUN apk --no-cache add rocksdb-dev --repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing

Installing rocksdb-ruby fails with:

...

Start by reviewing ext/rocksdb/extconf.rb and the C++ extension files, especially rocksdb_batch_rb.cc and rocksdb_batch_rb.h, then reproduce the failure using the Dockerfile with Alpine's rocksdb-dev 7.0.2. Done means the native extension compiles successfully against that RocksDB version.
