What I never understood is that nvidia-driver fakes dep on libGL, only to 
replace it. Is the rationale for that, that it eases the pain for the end user 
when uninstalling nvidia-driver, by still having a libGL around? Or is libGL 
needed for the opengl headers?
I think things are a lot less complicated if nvidia-driver is one of the 
choices for libGL and that if one wants to stop using it, one does:
portmaster -o graphics/libGL nvidia-driver-\*
