I have just hit this problem with grub-mkrescue. xorriso was not installed (I was using a netbook with no dc/dvd) but needed a usb rescue disk.
I note that grub-common suggests xorriso and agree that it should not depend on it. But is there any chance that the error message when xorriso is not found could make it clear that "xorriso" is a missing program/package rather than a missing file as I first supposed? ael -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
