Hi, The spamoracle source package contains two packages: Package: spamoracle Architecture: alpha amd64 arm i386 ia64 kfreebsd-i386 powerpc sparc Package: spamoracle-byte Architecture: all So it's perfectly normal that there's nothing to build on s390. This is an issue in the Debian build system which has already been debated (maybe someone on the d-o-m list will remember where). Cheers, Samuel.
