Doesn't recognize Ubuntu native packages as Ubuntu packages

Since the package doesn't have Ubuntu specfic versioning, how would Lintian know not to apply the Debian tests?

Checking distribution instead of version, I guess. I'm currently looking at the code and will try to propose a patch.

By the way, when checking the .changes instead of the .dsc, there is another false positive:
E: ubuntu-dev-tools_0.45_source.changes: bad-distribution-in-changes-file intrepid

So the bug actually is that lintian doesn't recognize Ubuntu native packages as Ubuntu packages.

Here is the patch (debdiff for jaunty even). Please review and, if it's fine, upload. In this case, I will then make sure it is forwarded to Debian.

Subscribing u-m-s, and Colin, given that he's one of the Debian uploaders.

There's a pending sync request for lintian 2.1.0. Would you please ensure
your patch is good with 2.1.0 and perhaps update the debdiff (I haven't
actually reviewed the patch - doing bugmail through my phone).

Patch will try to match $distribution on all <CHANGELOG> lines, not just the first.

minor note: noneed for " .*$" after ";" in dist matching regexp

Here is the debdiff against 2.1.0. Scott: I closed your sync request, so that everything (sync + patch) is done in a row.
Loïc: I fixed what you describe in your first remark, but didn't change the regexp: the " .*$" part doesn't seem mandatory indeed, but it doesn't hurt either. I prefer to keep so that it's clear how the line is splitted and which part we are taking. If there is another reason to not keep it that I missed, feel free to remove it when uploading (whoever uploads the package).

Thanks, looks good. I've sponsored the upload.

This bug was fixed in the package lintian - 2.1.0ubuntu1

    + [ADB] Ignore non-dependency fields when considering whether a
      versioned dependency is satisfied by the perl core packages.
      Based on a patch by Niko Tyni. (Closes: #500720)

      Module::Build now comes with Perl. Thanks, Raphael Hertzog.
      (Closes: #506697)
