You could prefix the Kino package to be installed in /opt/kino for example, and the include the xorg libraries in /opt/kino/lib.
Then to run Kino from that location, and using the xorg libraries installed there, use an ajusted library path variable:
By running kino like this, it will use the libraries in /opt/kino/lib first. This way you also don't need to change /etc/ld.so.conf for the libraries to be found.
BTW, this in an ugly way to do things, so its not encouraged for "everyday" use. When its necessary, then at least it keeps potentially "dangerous" things compartmentalized.
