I was clearing out hard drive space on my Macbook Air and I deleted Xcode. Has anyone had any problems with using ruby and/or Gosu without Xcode?
When I installed Gosu I had to open Xcode and agree to the terms so that Gosu would download. I think It needed command line tools or something to get Gosu working.
Now that I've deleted Xcode, Gosu seems to be working fine without it.
Will this give me any problems in the future?
You will need Apple's C/C++ compiler to install new versions of Gosu or any other C-based RubyGems, like Texplay, EventMachine etc. It doesn't have to be Xcode, you can also use Apple's command line toolchain: http://apple.stackexchange.com/a/106716
If the current version of Gosu is all you need in the foreseeable future, you don't need to reinstall anything, though.
The same applies to SDL 2, which you've probably installed using Homebrew.
