Usually there are two Ruby packages on Debian-ish distributions, ruby and ruby-dev. You need ruby-dev for the mkmf library.

If the Ubuntu instructions on this Wiki page work for you, please add "last tested on Linux Mint x.y.z" to the section header, thanks!

Sorry, I think I meant 'heading', not 'header' - the bold part that says

> Ubuntu (last tested on Trusty Tahr (14.10.1), with Gosu 0.8.6) / Linux Mint (last tested on Linux Mint 17.3)

now. Anyone who's logged into GitHub can edit the wiki. Almost everything on this page was contributed by Linux users who found this page and added to it.
