If you refer to the recent switch from sbuild-using-schroot to
sbuild-with-unshare-backend in the Debian autobuilders, no, I don't
think so.

I can build ruby-chef-utils in trixie, but I can't build it in unstable,
using the unshare backend in both cases, so my guess is that some
build-dependency is different from trixie to unstable.

However, if by "policies how to build a package" you refer for example
to things that dh_ruby does or does not, then yes, that would be
a good candidate to explain the difference.

(Hopefully somebody from the ruby team can look at this and provide a
better answer, as I'm just a QA tester here).

Hmm, please do not send binary .deb packages to bug reports... We work
with source code here.

The issue I reported happens when building the source package
(FTBFS = Fails To Build From Source). I take the source code
of all Debian packages and try to build them the standard way.
Then I report every case where the build fails.

Therefore, a more recent .deb binary package does not help here. Also,
I can only test packages in unstable.

I assume you are speaking as the author here. The Debian Ruby Team
will probably care about this issue sooner or later, but if you really
want to reproduce the problem (to be able to determine if a new
version fixes it or not) my best advice is that you first learn how to
build a package from source the Debian way, using sbuild:
