Brake booster leaking power steering fluid?

[halflife]

I think my brake booster is leaking power steering fluid? Has this happened to anyone? there was fluid coming from the drivers side wheel well and running down to the subframe connectors. there was also a drop on the very top of the steering shaft. From the top i could not tell exactly but looking down on the drivers side by the brake resevior. there is a little block that power steering lines go into, not sure what it is called but the thing behind the brake resevior is it called the brake booster has the lines going into it. under it basically on top of the wheel well there is a bunch of gunk built up. I am gonna pull the wheel well out tomorrow night to get a better look but i think it has to be leaking from that block or the booster??
