I think wine dlopen()s many libraries instead of linking dynamically to them. 
This makes the build environment more independent of the runtime environment, 
and we can provide binary builds with all features enabled, and they will 
still run if the user's system does not have all the libs.

We had an issue like that with libGL.so a long time back, and it was fixed by 
changing some parameter to dlopen. Does anyone remember what that was, and if 
this can be done for the other libraries too?

Lionel, can you provide us with a list of libraries where LD_PRELOAD does not 
work correctly? This should help to track down the bad ldopen calls.
