Unfortunately, this will cause an error in some versions of ruby due to a bug in bundler. Users will just have to install psych themselves when needed. I'm using ruby 1.9.3 without psych, and it works fine. I don't plan on addressing the 16 bit graphics issue because few poeple will run into that problem, but thanks for the report!!!
