Quoting Mathieu Malaterre <mathieu.malaterre@gmail.com>:
[Sorry I was not subscribed when I got the answer from George Danchev] So anyway I tried the --same-arch flag and it *seems* to be working on alpha (there is no log reporting failure), but it clearly does not work on armel: Here is a copy of the control file: ... Package: libgdcm-cil Section: cli-mono Architecture: i386 lpia kfreebsd-i386 powerpc amd64 kfreebsd-amd64 ia64 arm armeb sparc s390
you still have armel specified in the architecture of libvtkgdcm-cil package section, while you don't have alpha listed for anywhere, that's why is worked for alpha, but not for armel.
