How would having a "find the latest version" help here?  The point is Apple does not want you to use *any* version of libcrypto in /usr/lib: they are there only for old versions of third-party apps that were linked to a specific then-current version of the system libcrypto with a specific ABI.  For libssl and libcrypto, Apple has been saying for many releases you need to supply your own versions; they haven't been supplying the header files for them in the SDKs for several releases and now this.  If an app *is* trying to use an old version (which it shouldn't!), it does need to munge a specific version.
