Yeah, it's very unfortunate, that's exactly the library that you'd
like to be able to depend on, so we checked specifically. But it turns
out that openssl has broken ABI over the relevant time-period, so
there's no choice, you can't rely on the system version and have to
statically link :-(.

Though I guess this is no worse than than if you want to distribute a
wheel that needs openssl on Windows.
