Even if the app links against both libraries don't you have the same 
basic problem. i.e., the library found at link time may not be the same 
one as found at run time?
I don't see any automatic way of getting round this, and I really hate 
those foo-config scripts.
The version suffixes on shared libraries are *supposed* to avoid this 
issue (but don't work while APIs are changing, of course). While things 
are in flux, I think you just have to be careful with LD_LIBRARY_PATH 
if you have libraries in non-standard locations.
