Hi,

thanks for this answer that explains in a very clear way why it did not 
work.
I believe I will have to bundle the library for the moment as you said. 
I will also try to recompile the RPM to try if it is possible to build 
the static lib but with few hope to get something working...

Really thanks for all your explanations,
Fabien
