pre-bake it for a couple of minutes to dry it out. to do this, line it with foil, and weigh it down with some dry beans or rice so it won't shrink. bake @ 350 for about 7 minutes. then fill it.
Also, if your filling is particularly runny, it will also cause this to happen once it is baked. adding a little extra fat to the recipe works well to emulsify the egg/pumpkin mixture so it does not weep liquid after it is cooked.
