Indeed. I rebuilt Scilab with the rpath and it works. Thanks for the
tip!
I wonder what is the best solution:
* move all content of /usr/lib/scilab/ to /usr/lib/ (it is more than 70
shared lib). But I would have to do that upstream also just for this
Python module.
* add the rpath for the libraries in /usr/lib/scilab/
(Sorry if I leave the scope of Python here)
