There is not an issue here at all. As it was said above though, make sure that you take this is an expert in Aluminum welding. They will want to heat the block before welding then allow to slowly cool in an over after.
I machined an aluminum Donovan block years ago that grenaded in a sprint car. A shop in Sacramento took 6 hours and welded the block back together. Your situation doesn't sound nearly as drastic.

I would be curious as to why it is leaking on a new engine.
If it is a crack, did it get dropped?? I would think there would have to be some kind of mark on the block as they do not just crack.
Or is it an actual casting issue and is pourous in that area?? If this is the case, then a simple weld up may or may not cure it and it could be weak in that area.
Not trying to wish bad luck on this as it has the potential to be a great deal, but these are questions I would be looking into if I were condering buying and using this block. Hopefully it ends up being an easy fix.
