Eventmachine, OpenSSL, and Windows

[Alex Wood]

Hello,

I'm working on a feature (https://github.com/jekyll/jekyll/pull/5142) for the Jekyll static site generator.  I'm using EventMachine to run a WebSockets server (em-websockets).  Unfortunately, I'm having an issue with eventmachine's native extensions on Windows in the Jekyll CI environment.  I'm getting an error, "Encryption not available on this event-machine".  I've read https://github.com/eventmachine/eventmachine/wiki/Building-EventMachine and I believe I'm linking to OpenSSL and getting the native extensions compiled but I am still seeing the same error:

bundle exec gem pristine eventmachine

As you can see, after a `bundle install`, I'm running `bundle pristine` and then `bundle exec gem install` with the appropriate flags as mentioned in the wiki article I linked earlier.  Using `bundler config` to add the arguments did not seem to make an difference at all for me.  In addition to the log reporting that the native extensions are built, I can also see an `ssl.o` file in the `ext` directory of the evenmachine gem.

If anyone has any additional insight into what "Encryption not available on this event-machine" means or if there's a better way to tell if eventmachine linked successfully to OpenSSL, I'd appreciate some help!
