I had the same and fixed these in the gcomprixo branch this week end. I
just ported my hack back in trunk. Please have a test.

Your fix proposal makes sense but I am not sure it's the good way
because we would link staticaly libgnomecanvas with gcompris binary and
the libpython binding. That probably works but it's strange.
I made a hack to force missing symbols to be included in gcompris core.
Their is probably a better way but at least, we don't have the code
twice. If somebody understand the issue, a clean solution is welcome.

What happens is that we compile statically gcompris and libgnomecanvas
but some unused symbols are stripped. But our python binding needs them
and we fail to dlopen it.
