I'd ask the author of B first, why the H*** he has to use the same
library name that is already used by A, especially since he uses A.
That is broken in itself because if you install A and B with the same
prefix, B is broken.
If you really need such specific linker behaviour (and who tells you
that all linkers behave like this?), you actually already messed up.
