However, I can't do this for /usr/lib/libvpx.so and the bins, that perhaps aren't needed from the old package. $ pacman -Ql libvpx libvpx /usr/ libvpx /usr/bin/ libvpx /usr/bin/vp8_scalable_patterns libvpx /usr/bin/vp9_spatial_scalable_encoder libvpx /usr/bin/vpxdec libvpx /usr/bin/vpxenc libvpx /usr/include/ [snip] libvpx /usr/lib/ libvpx /usr/lib/libvpx.so libvpx /usr/lib/libvpx.so.1 libvpx /usr/lib/libvpx.so.1.3 libvpx /usr/lib/libvpx.so.1.3.0 libvpx /usr/lib/pkgconfig/ libvpx /usr/lib/pkgconfig/vpx.pc libvpx /usr/share/ [snip] $ ls -hlG /usr/lib/libvpx.so* lrwxrwxrwx 1 root 15 Dec 7 2013 /usr/lib/libvpx.so -> libvpx.so.1.3.0 lrwxrwxrwx 1 root 15 Dec 7 2013 /usr/lib/libvpx.so.1 -> libvpx.so.1.3.0 lrwxrwxrwx 1 root 15 Dec 7 2013 /usr/lib/libvpx.so.1.3 -> libvpx.so.1.3.0 -rwxr-xr-x 1 root 1.7M Dec 7 2013 /usr/lib/libvpx.so.1.3.0
