Looks like the return line gasket may have been leaking but I am not sure about the big oil stain on the turbo. Does the car smoke? It appears that the return line gasket could have been leaking as there is some oil on the bottom of the return line waiting for gravity to catch up with it. I see there is coolant on the turbo but I assume that it was probly spilled when removing the turbo. Is there a lot of shaft play? That would indicate if there are bad seals.

Is there any sign of a oil leak on the top side of the turbo? Does the feed line look like it was leaking?
