It's not saying that it can't find the file, but rather that it cannot find a
package containing /lib/libGL.so.1 or /usr/lib/libGL.so.1 (as either a link or
a file).

Because the ogl-select runtime service sets the links to the nvidia or mesa
version as needed for the system.   This is also why they're not packaged -
the package can't set the link differently based on the hardware installed
on the system.

This is why xscreensaver has a workaround for this in its manifest:

# pkgdepend can't follow the runtime generated symlinks to libGL
set name=pkg.depend.bypass-generate value=libGL\.so\.1

[... all the files in the package ...]

# Second half of workaround for pkgdepend not handling libGL's magic properly
depend type=require fmri=__TBD pkg.debug.depend.file=usr/lib/mesa/libGL.so.1
