I wrote Depends:, but I meant Build-Depends:, sorry if this was
confusing. The goal was to declare that my rules file needed a more
recent version of dpkg with the "dpkg-buildflags --export=configure"
feature, which fails on Squeeze.

As said above: hardening build flags:
dpkg-buildflags --export=configure

I wanted to declare that, for an eventual backport of my package.

So, how do you keep track of each new feature? Could you take that
dpkg-buildflags as example, and tell me how I'm supposed to find out
when, in this long history of upload, the feature was added?

Am I suppose to read the changelog of dpkg, which is really HUGE, in the
hope that maybe, I'll find my way to guess whats the lowest version in
the history? Or should I read all Git commits? How can I make sure that,
even if the feature is there, there's no issue with it, fixed later? Or
is there any better trick? Or even better: what would be the point in
build-depending on a version that will *never* be in Debian anymore?

If your proposal is to effectively read the changelogs, then I don't
agree with such a loss of time with no valid advantage.


P.S: I don't think this is very interesting. My package has been
corrected in SID (and in fact, it never had, in SID, the wrong
dependency that I talked about, -4 release had no build-depends at all
on dpkg) and a backport is now possible. Can we move on?
