x11/nvidia-driver incompatible with portmaster?

It's a bad idea because it's sensitive to the order of
(de)installation.  It's always been unfortunate that nvidia-driver
collides with xorg-server and libGL.  It would be better if
xorg-server and libGL were patched to install a linker script instead
of the libGL.so and libglx.so symlinks, which would favor the
nvidia-specific libraries over the generic libraries if the former
were present.  Or if nvidia-driver didn't replace the shared libraries
of the other ports, but used additions to libmap.conf(5) instead.
