That problem comes entirely from my own laziness, sorry about that. It's very hacked together because I built it on something I want to expand later, and most of it isn't in place yet, but unless I made a mistake with the source archive, you can put it into `~/quicklisp/local-projects/` and then `(ql:quickload :metacard)`, then `(load "bleach-2.lisp")`, then `(metacard::set-up-framebuffer)`, then `(metacard/glfw:make-os-window)`. Unless I made a mistake that should work.
Alternatively, you could run the Windows version in Wine, which seems to work perfectly.
