Thanks. This seems to be a build system corner case that only happens when the Configure run is split in two with -E and -S, which we do for the benefit of cross builds. I think it can be fixed by injecting a 'make depend' call at the end of debian/config.debian, mimicking what Configure does when run "normally" with -e. That would be preferrable to the dh --no-parallel workaround as it would not slow the builds. Could you please try if the attached patch fixes it? -- Niko Tyni nt...@debian.org

The Makefile dependencies are not quite robust for parallel builds if generate_uudmap is not pre-built (which happens during the 'make depend' phase.)
