Hi! While working on the "reproducible builds" effort [1], we have noticed that lordsawar could not be built reproducibly. The gama data archives, which are just tarballs, have files with the current time, the build user and varying permissions (depending on umask). The attached patch fixes this. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
