It would be a pretty simple hack to try dlopen'ing the basename() of the 
configured driver filename in e.g. $libdir/unixodbc and falling back if 
necessary.  Dumping libraries out of $libdir will e.g. speed up 
ldconfig, and reduce package size since the useless versioning symlinks 
can be dropped.
