Issue between psych and mini_racer on platform x86_64-linux

[jplanza]

Hello folks. I'm pretty new to Ruby but I thought this might be interesting for someone with more knowledge to look into. To keep this short, I installed the debug gem on MacOS to solve an unrelated runtime problem. I sorted everything out locally and had a working bundle there, so the next step was to go back to a Docker container; except the builds started failing in Linux. It turns out that debug has psych in its dependency chain and will build fine on Darwin but not Linux.

I was able to workaround this by removing the debugger, so I don't actually need any help here. But I'm offering this up in case someone can make better sense of it and perhaps solve it for the next person using this gem. Please let me know if you need any further information about my build environment.
