Yes. Actually, bsd.port.mk uses the ``-O'', instead of the ``-W''. Search for 
PACKAGE-DEPENDS-LIST (a rather grotesque contraption, BTW). Thus it is still 
prone to mistakes such as recording dependency on meow, when libmeow.so was 
installed by meow-devel or something.

But it is *still* perfectly safe without the shared libs major numbers. Using 
those without a _real_ need to is useless and breaks the perfectly legitimate 
scenarios outlined earlier in this thread.

Doing so _knowingly_ is simply capricious...
