then we need to handle it ?  there's no guarantee the ABI is compatible ...
if it was, then it probably wouldn't have changed SONAMEs.

usually the libxxx.so symlink isn't generated on runtime systems.  you need
to install extra dev packages to get it.  so loading the SONAME directly is
almost always the right thing.
