Issue with ffi gem dependency

[twoesplease]

Lately in my projects that use pi_piper, I'm getting the following in my stack trace when the code tries to initialize a new pin object:

        12: from watch_chat_waits.rb:98:in `light_it_up'

"light_it_up" is the method name I'm using to manage the logic for turning the pin on & off. "pin" is the variable I'm using to hold the pin object.

Looks like there may be an issue with the ffi library?

I didn't see any similar issues to this one, and I tried updating the pi_piper and ffi gems with the same result.

Let me know if there's any other info I could share that'd help!

Thanks.
