So nvidia-something port needs to install libGL-nvidia.so.1, and
not libGL.so.1.

Should I repeat what I said already, or can I just point to my other
message ?

The renames of the libGL.so inside the packages are orthohonal to
package splits. The issue is that libGL.so.1 installed by both packages
(graphics/libGL and x11/nvidia-driver). And not that the nvidia-driver
contains some other stuff.
