We really should be using -rpath when building to specify the location of 
libraries (giving an $ORIGIN-relative path to each of the install locations).  
This will also require us to install shell scripts, rather than symlinks, into 
bin/ for starting tools from a default path, because otherwise the rpath will 
be relative to the wrong thing (as I discovered when using rpath for a library 
shipped inside the .app bundle).
