[cl-cairo2-devel] Can't run example

I'm just starting trying out cl-cairo2 (again). I needed to make one modification in order to compile/load, because Debian does not make versionless shared object libraries in the production packages, I needed to change the line in cl-cairo2/libraries-x11.lisp, to specify the version of libX11.so: (:unix (:or "libX11.so" "libX11.so.6")) I've attached a patch.

Now my problem: I can't load the example in x11-example. It seems there is a function create-xlib-context which is called; that in turn is defined in xlib-context.lisp which doesn't seem to be in any of the asd files provided. Should this be loaded?
