 	* On Ubuntu/Debian-like Linux distributions, you need `libgl1-mesa-dev` and `xorg-dev` packages.
 	* On CentOS/Fedora-like Linux distributions, you need `libX11-devel libXcursor-devel libXrandr-devel libXinerama-devel mesa-libGL-devel libXi-devel libXxf86vm-devel` packages.
 	* On FreeBSD, you need the package `pkgconf`. To build for X, you also need the package `xorg`; and to build for Wayland, you need the package `wayland`.
+	* On NetBSD, to build for X, you need the X11 sets installed. These are included in all graphical installs, and can be added to the system with `sysinst(8)` on non-graphical systems. Wayland support is incomplete, due to missing wscons support in upstream GLFW. To attempt to build for Wayland, you need to install the `wayland libepoll-shim` packages and set the environment variable `PKG_CONFIG_PATH=/usr/pkg/libdata/pkgconfig`.
 	* On OpenBSD, you need the X11 sets. These are installed by default, and can be added from the ramdisk kernel at any time.
 	* See [here](http://www.glfw.org/docs/latest/compile.html#compile_deps) for full details.
 * Go 1.4+ is required on Windows (otherwise you must use MinGW v4.8.1 exactly, see [Go issue 8811](https://github.com/golang/go/issues/8811)).
