XS.c: loadable library and perl binaries are mismatched (got handshake key 0xcd00080, needed 0xce00080)

That error probably means the carton cache was built locally instead of inside the container, and they aren't running the same distro version.

The dummyplug Dockerfile does this:

RUN rm -r /app/dummyplug/local
RUN carton && rm -r local/cache && rm -r ~/.cpanm

Fixed dockerfile: https://github.com/fastly/kryten-api/pull/135/commits/1ff852c71ea8d74de4063eb2cf579fba3794eb53
