Yes, python-all-dev depends on libpython-all-dev, but we want the build architecture python-all-dev and the host architecture libpython-all-dev. Thus the dependency doesn't get us the correct version. Note the ":any". Yes, this is weired. No, I don't understand why we didn't make dependencies on python-all-dev just work (by swapping python-all-dev and libpython-all-dev and reversing the dependency). > Hm, that would make the package not syncable to Ubuntu and other > derivatives. > I wonder if it would be better to conditionalize on dpkg-vendor > (DEB_VENDOR, /usr/share/dpkg/vendor.mk) instead. Ubuntu is not a valid value for --with-distro. I guess it treats Ubuntu as Debian. Furthermore, the flag is only passed for cross compilation and thus doesn't affect native compilation. So I think we should first make this work for Debian (while not breaking native Ubuntu builds) and then Ubuntu can provide the dpkg-vendor code if necessary. Helmut
