[jlnr]

The message about SDL2_ttf might be misleading. I think the real problem is that I forgot #include <cstdint> in Color.hpp, and somehow no other compiler has caught that mistake.

To make sure that this has really fixed the issue, I've pushed gosu-0.11.1.pre1, so please run gem install gosu --pre and see if that works.

[Sylvain303]

Yes, it worked to install. Thanks.
