Small Leak from Water Pump Weep Hole Tolerable?

I have a replacement new water pump, with about 3K miles on it. I have it torqued to the proper specs, the new belts were adjusted to new and then readjusted to "used" specs with a Krikit as per the manual, and I use the right mix of MB/Zerex G-05. I have a tiny - I mean, tiny - leak coming from the lower weep hole of the pump. In a month of this, I've seen no drop in my expansion tank; but I can tell the pump is leaking a little because of the residue left on my (polished) parts like the water pump, alternator, power steering pump, etc. This seems to happen if I drive the car, let it sit for a few hours, and drive it again. I've never actually seen any liquid but I have felt the weep hole damp after driving.

Again, I'd be surprised if the total amount of the leakage over the course of a month (driven lets say every other day) has amounted to a thimbleful, and I probably would not have noticed it on unpolished parts.

Does anyone think this is serious? Enough to replace it? Gee, I hope not...
