Not sure why e2fsprogs is BD-uninstallable on amd64?

[Theodore Ts'o <tytso@mit.edu>]

Hi,

At the moment, according to buildd dashboard for e2fsprogs[1], the package
is uninstallable on amd64, kfreebsd-amd64, and kfreebsdi396.

[1] https://buildd.debian.org/status/package.php?p=e2fsprogs

The reason cited is:

e2fsprogs depends on missing:
- e2fslibs:amd64 (= 1.43.8-2)

However, this doesn't make any sense to me.  There are no build
dependencies on e2fsprogs:

   Build-Depends: gettext, texinfo, pkg-config, libfuse-dev [linux-any kfreebsd-any] <!pkg.e2fsprogs.no-fuse2fs>, libattr1-dev, debhelper (>= 9.0), libblkid-dev, uuid-dev, m4

And there with 1.43.9-1, there are no install-time dependency from
e2fsprogs to e2fslibs (any more):

   Pre-Depends: libblkid1 (>= 2.17.2), libc6 (>= 2.14), libcom-err2 (>= 1.42~WIP-2011-10-05-1), libext2fs2 (= 1.43.9-1), libss2 (>= 1.34-1), libuuid1 (>= 2.16)

Previously we had such a dependency:

   Pre-Depends: e2fslibs (= 1.43.8-2), libblkid1 (>= 2.17.2), libc6 (>= 2.14), libcomerr2 (>= 1.42~WIP-2011-10-05-1), libss2 (>= 1.34-1), libuuid1 (>= 2.16)

... but that was before e2fslibs was renamed to libext2fs2 in
1.43.9-1.  And since e2fslibs is built as part of e2fsprogs, I'm not
sure why this would be a dependency that would case e2fsprogs to be
BD-uninstallable in the first place.

Can you explain what might be going on?

Many thanks!!
