I've used that very library before myself, so I don't understand the problem really. It's a standard DIL16 package. If you use a grid proportional to the standard 0,1"/2,54mm, it will align the way it should. So my guess is, you set your grid to something else...
Ah well, you are talking about the schematic symbol... I tried that ULP you mentioned and it says to use it only in the schematic. Then I remembered that I modified the library when I used it first. Take a look at the attachment .
