I was cleaning up my 'abi_x86_32' use flags and I started receiving the following preserved libs notice after running 'emerge --depclean': !!! existing preserved libs: >>> package: x11-libs/libXdamage-1.1.4-r1 * - /usr/lib32/libXdamage.so.1 * - /usr/lib32/libXdamage.so.1.1.0 * used by /usr/lib32/libGL.so.1 (preserved) * used by /usr/lib32/libGL.so.1.2.0 (preserved) >>> package: x11-libs/libXxf86vm-1.1.4 * - /usr/lib32/libXxf86vm.so.1 * - /usr/lib32/libXxf86vm.so.1.0.0 * used by /usr/lib32/libGL.so.1 (preserved) * used by /usr/lib32/libGL.so.1.2.0 (preserved) >>> package: x11-libs/libdrm-2.4.65 * - /usr/lib32/libdrm.so.2 * - /usr/lib32/libdrm.so.2.4.0 * used by /usr/lib32/libGL.so.1 (preserved) * used by /usr/lib32/libGL.so.1.2.0 (preserved) >>> package: x11-libs/libXfixes-5.0.1 * - /usr/lib32/libXfixes.so.3 * - /usr/lib32/libXfixes.so.3.1.0 * used by /usr/lib32/libGL.so.1 (preserved) * used by /usr/lib32/libGL.so.1.2.0 (preserved) >>> package: media-libs/mesa-11.0.6 * - /usr/lib32/libglapi.so.0 * - /usr/lib32/libglapi.so.0.0.0 * - /usr/lib32/libGL.so.1 * - /usr/lib32/libGL.so.1.2.0 * used by /usr/lib32/libnvidia-fbc.so.361.28 (x11-drivers/nvidia-drivers-361.28) * used by /usr/lib32/libnvidia-ifr.so.361.28 (x11-drivers/nvidia-drivers-361.28) >>> package: dev-libs/expat-2.1.0-r5 * - /usr/lib32/libexpat.so.1 * - /usr/lib32/libexpat.so.1.6.0 * used by /usr/lib32/libGL.so.1 (preserved) * used by /usr/lib32/libGL.so.1.2.0 (preserved) >>> package: x11-libs/libxshmfence-1.2 * - /usr/lib32/libxshmfence.so.1 * - /usr/lib32/libxshmfence.so.1.0.0 * used by /usr/lib32/libGL.so.1 (preserved) * used by /usr/lib32/libGL.so.1.2.0 (preserved) I tried reinstalling x11-drivers/nvidia-drivers with the 'multilib' USE flag disabled and I received the following error: x11-proto/kbproto:0 (x11-proto/kbproto-1.0.7:0/0::gentoo, ebuild scheduled for merge) conflicts with >=x11-proto/kbproto-1.0.6-r1[abi_x86_32(-),abi_x86_64(-)] required by (x11-libs/libX11-1.6.3:0/0::gentoo, installed) I don't really know if media-libs/mesa[abi_x86_32] is required by the 'multilib' USE flag or not, but that's what I'm assuming.

These minimal flags in package.use allowed for 'emerge -upvD --newuse @world' to run without any dependency errors. sys-libs/zlib abi_x86_32 x11-libs/libX11 abi_x86_32 x11-libs/libXext abi_x86_32 x11-proto/kbproto abi_x86_32 x11-proto/xcb-proto abi_x86_32 x11-proto/xextproto abi_x86_32 x11-proto/xproto abi_x86_32 The preserved libs notice occurred for nvidia-drivers with the above flags set. emerge @preserved-rebuild did not fix the issue. Adding 'virtual/opengl abi_x86_32' or 'media-libs/mesa abi_x86_32' and their respective dependencies to package.use and rebuilding prevents the preserved libs notice from occurring.
ebuild version is x11-drivers/nvidia-drivers-361.28
The nvidia-drivers libraries should link to *a* /usr/lib32/libGL.so but since we're shifting those libraries around with the old eselect-opengl implementation, this creates a false link between them. I am still not sure what happened in your case. Please post your output of `emerge -vpq app-eselect/eselect-opengl`.
