Artoolkit does not load textures in OS X

Hello i am using the lat开发者_StackOverflowest version of artoolkit, and succesfully compiled simplevrml, but it doesn't show any textures not even the ones in the bud_B example.

Does anyone have a similar experience or problem or have solved this?

Thanks in advance.
