This is not really true.  We could support both 6.3 and 6.5 by writing some
configure logic to detect the version and then using #ifdef's in the code.
The question is whether or not we *want* to support both 6.3 and 6.5.  One
reason we might want to is that Ubuntu includes binary packages for OCC 6.3.
