You need to give more information -- why can't the dependencies be modelled?
If you have the raw data from which the proportions are calculated, you can
use a randomization test, I guess. The Chen-Stein method is one way of
modelling a sum of dependent Bernoulli random variables, but it needs the
problem stated more precidely..
