Doesn't install with rocksdb 7.0.2

[mrkamel]

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:

...
