[R-pkg-team] Bug#1054323: r-cran-tmb: autopkgtest needs update for new version of rmatrix: Package version inconsistency detected

Source: r-cran-tmb
Version: 1.9.6-1
Severity: serious

Dear maintainer(s),

With a recent upload of rmatrix the autopkgtest of r-cran-tmb fails in 
testing when that autopkgtest is run with the binary packages of rmatrix 
from unstable. It passes when run with only packages from testing. In 
tabular form:

                        pass            fail
rmatrix                from testing    1.6-1.1-1
r-cran-tmb             from testing    1.9.6-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of rmatrix to 
testing [1]. Of course, rmatrix shouldn't just break your autopkgtest 
(or even worse, your package), but it seems to me that the change in 
rmatrix was intended and your package needs to update to the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from rmatrix should really add 
a versioned Breaks on the unfixed version of (one of your) package(s). 
Note: the Breaks is nice even if the issue is only in the autopkgtest as 
it helps the migration software to figure out the right versions to 
combine in the tests.
