    Package: dpkg-dev
    Version: 1.22.15

    Hello Guillem et al.

    I was going to ask ftpmaster to remove the "hello-traditional" package,
    but decided to still make a "last release" so that it's archived in snapshot.d.o.

    To my surprise the package failed to build on hurd-i386:

    [...]

    Is this a bug in dpkg-dev?

    ( The package now has autotools-dev as its only build-dependency,
    which is clearly strange but not technically a bug )

    Thanks.

    Is this a bug in dpkg-dev?

    That would seem a bit strange as I do not recall recent changes that
    would affect his.

    In any case, just to make sure, I was unable to reproduce this on my
    hurd-i386 VM. I even tried on an amd64 chroot to remove the
    build-essential and gcc packages (which is where the arch comes from),
    but those fail gracefully too.

    ( The package now has autotools-dev as its only build-dependency,
    which is clearly strange but not technically a bug )

    This looks like the chroot might have issues? Perhaps the prefixed
    fixchroot command in front of dpkg-buildpackage is interacting badly
    with it? (Which seems specific to the hurd-* ports).

    I'm CCing the debian-hurd list.

    Thanks,
    Guillem
