Then how did you try to install the spkg? I double-checked the log for the install of your package, and indeed, there is a pleasant message describing the problem. However, it's embedded in the middle of what looks like a disaster alert :-} There are ~50 lines of output, of which two, in the middle, mention the missing GAP database(s). Can the dependency failure be detected before, say, downloading your .spkg? That way, it wouldn't be quite so unobtrusive, and the failure would look less like a real error.
