re: Dryer leaking condensation on ground.

I sounds to me what could be happening as the warm/hot humid air, which has a high dew point temperature, is vented from the dryer up the vent/flue pipe, as it comes into contact with the cold metal vent pipe in the attic, near the roof line, the water vapor in dryer exhaust air is condensing into liquid water and running back down the vent and pooling up at the bottom of the dryer.
It’s physics/psychrometrics - when the dew point temperature of air containing moisture contacts a colder surface it condenses to liquid water. I doubt if it’s a dryer/mechanical problem per se.
I suspect It’s likely only a problem that is occurring in winter and not when the temperature in attic is warm/hot.
Short of being able to vent the air horizontally over a short distance out the house, you could try insulating the portion of exhaust vent pipe that is in the attic up to the roof to see if that corrects the issue, and/or you might need a booster fan to get the dryer vent exhaust air out of the house more quickly. Here is an article with suggestions LINK
Anyway, just additional thoughts for you to investigate/consider.

Well that's something I never thought of. The dripping started this winter. It mainly pools under the dryer itself rather than dripping from the vent from wall. But I will look. That's an interesting thought.
