--- Comment #3 from Alexey Dokuchaev <danfe at FreeBSD.org> ---
Right, and I think this simple logic can be improved.  Currently nvidia-driver
conflicts not just with xorg and libGL, but also libEGL and libGLESv2.

I'm playing with the idea to stop assuming of any particular order in which
these ports/packages are installed, and create symlinks (hardlinks only
complicate things here) upon install/deinstall in the following way:

In post-install:
        ...
        /bin/ln -sf .nvidia/libGL.so.1 ${PREFIX}/lib
        /bin/ln -sf .nvidia/libGL.so ${PREFIX}/lib
        /bin/ln -sf .nvidia/libEGL.so.1 ${PREFIX}/lib
        /bin/ln -sf .nvidia/libEGL.so ${PREFIX}/lib
        /bin/ln -sf .nvidia/libGLESv2.so.2 ${PREFIX}/lib
        /bin/ln -sf .nvidia/libGLESv2.so ${PREFIX}/lib
        /bin/ln -sf .nvidia/libglx.so ${PREFIX}/lib/xorg/modules/extensions

In post-deinstall:

# Conditionally put links to files (i.e., if they were previously installed)
# $1 common path (prior to hidden directory)
# $2 remainder (e.g., .foo/libbar.so)
maybe_link_back()
{
        [ -f "$1/$2" ] && /bin/ln -sf "$2" "$1"
}
        ...
        maybe_link_back ${PREFIX}/lib .libGL/libGL.so.1
        maybe_link_back ${PREFIX}/lib .libGL/libGL.so
        maybe_link_back ${PREFIX}/lib .libEGL/libEGL.so.1
        maybe_link_back ${PREFIX}/lib .libEGL/libEGL.so
        maybe_link_back ${PREFIX}/lib .libGLESv2/libGLESv2.so.2
        maybe_link_back ${PREFIX}/lib .libGLESv2/libGLESv2.so
        maybe_link_back ${PREFIX}/lib/xorg/modules/extensions .xorg/libglx.so

Similar changes will have to be added to "conflicting" ports (libraries and X
server).
