What needs to be done to stop my ducts from sweating copiously?

The A/C ducts for my house are in the crawl space. There's pools of water under the ducts, and the insulation around the ducts is wet. I need to get this resolved because mold is start to grow on the joists. But what needs to be done?

Let me provide a bit more info in case that helpful. The crawl space is about 2.5' high. The main duct runs lengthwise, right in the center. It covers at least 75% of the run. And in most places there isn't enough room to go over or under the duct. (There's a crawl spaces door at each end of the house.) The ground is covered 100% with a vapor barrier of 6 mil plastic. I should also mention there is a skirt vent ever 5' around the house. I also need to state the obvious. I live in S. Carolina where it's hot as hell and humid. "A screen door away from hell" describes summers here perfectly...

I did cut slits in the vapor barrier to drain the pools of water. I also removed the crawl space doors. But that's hardly a permanent solution. Do I need fans? New ducts? What?
