Exactly that would have been the preferred solution. :-)

It also blurs the line between OS (/usr/lib) and additional
software (/usr/local/lib) directories. However, both directories
are used by the linker, so it looks possible (and probably better
than messing with symlinks in /usr/local/lib). Problems _might_
occur when updating world.
