It is.  I'm not sure there's a clean answer for this sort of thing though. 
Normally, a library replaces earlier versions of that library, so they can
use the same files.  When you have a need to retain old versions - mostly
caused by ABI upgrades - you need to have completely separate directory
trees, resulting in unwanted redundancy.
