Comment 6 for bug 1253638

This seems to be a feature of DT_RUNPATH that is do not follow transitive dependencies.
The problem is ld linker since v2.27(debian), enables by default new dtags ( it uses RUNPATH instead of RPATH), so some dependencies may not been found at runtime. Of course add LD_LIBRARY_PATH env, will do the tric, but those who use rpath options, are specially whiching to avoid that.
