Of course. I'm not an expert in this, but I guess when you specify the lib 
directory it is going to use the first lib that is supposed to work.

I'm not. I think these are older ones, backwards-compatible.

symlinking won't help as this may affect other software. You have to get 
it out of the way, so the linker has a chance to find another lib.

Well, the problem is that you have several client libraries on the 
machine. AFAIK there is no way to specify a specific version of it, so you 
have to move the others out of the way when you build (by renaming). Later 
you can put them back.
