Name, Description and the list of filenames included in the package suggest to me that the package can and should be M-A:foreign – or in other words: Why is it allowed? * otherwise: Check if gyoto-bin can't be split up into a package which can be marked M-A:foreign and one which can be marked M-A:same. Rule of thumb: Don't make any package M-A:allowed as long as you haven't got a bugreport telling you it would be nice from some cross-folks (be it grader, builder, bootstrapper, …). Reason is that M-A:same/foreign is instantly useable/ful, but M-A:allowed is useless if nothing ends up depending on it with :any. Best regards David Kalnischkies
