Can not run the bin file

[rubyFeedback]

Could not find gosu-0.7.41 in any of the sources Run bundle install to install missing gems. Gem dependencies not met. To install: bundle install

^^^ could the hardcoded restriction be lifted?

I'd like to use the latest gosu. I am willing to adjust the code base to the new gosu too, but the hardblock in bundle confuses me a bit (I don't use bundler myself, only gem).
