When attempting to build the readme sample (and installing opengl freeglut3-dev, and randr xorg-dev libglu1-mesa-dev) I'm getting this:

error: aborting due to previous error
Could not compile `kiss3d`.

The readme says that the latest nightlies of rust are required, but that was edited a long time ago so is that still necessary?

I commented out the verify! line that the error references because to me it seemed like a somewhat optional assert kind of statement. That let it keep going but I still had errors with an ambiguous Vec3 in the sample which I changed to &na::Vec3::new... instead.

Now it builds through but at runtime I get thread '<main>' panicked at 'gl function was not loaded', ~/Projects/hello_world/target/debug/build/gl-f2eae2a83ed0cb03/out/bindings.rs:23202

I also tried removing those glut packages and installed glew instead but I get the same result.

Doesn't compile on latest (today's) nightlies.

It works when doing transmute.

Fixed by #70

This is due to the latest updates in gl-rs. glfw seems to be behind. Could you look into this @bvssvni?

@bjz Looking. I ran into some minor issues that we might want to check first. PistonDevelopers/glfw-sys#5, PistonDevelopers/glfw-sys#6, PistonDevelopers/glfw-rs#331.
