I tested opengl (both 32 and 64-bits) worked in my debian. The context is provided by x11. Perhaps some addons such as api/x11 are missing. Install that addon and try again. If it still fails, then install all addons. You can always un-install addons in pacman.
run demos by load '~addons/demos/opengl/simple/gldemos.ijs' load '~addons/demos/opengl/demo/gldemo.ijs' osmesa is not used at all because it now renders by using card hardware. mesa needed only if your video card driver cannot provide opengl which is unlikely except when you are using the framebuffer vga card driver. only libGL and libGLU are needed which should be present in all modern linux install. libX11 is used to provide context for renderring and it must be there unless x-window has not been installed. So I guess you need not worry those libraries.
