Hi Laércio,

Have you tried linking the external library as a shared object instead
of static? That way, the runtime loader should only try to bring it in
once.

You may be able to achieve the same result with static linking if you
manually incorporate that library archive once at link time, rather
than it getting repeated for each LB.
