Oh well - I might be wrong and it is "just" an overly strong interpretation by ftpmasters that I have experienced in the past. Or perhaps it is not an overly strong interpretation, but a real sensible one which has just not yet been codified in Policy. Do you find the reasoning I gave non-sensical? >> libmodule-build-perl exists as a package, so simply favoring that >> over the perl-provided version should work _and_ be deterministic >> _and_ work on more relaxed environments permitting undetermnistic >> fallbacks (read: backporting with pbuilder or variants like >> cowbuilder): >> >> Build-Depends: libmodule-build-perl (>= 0.40) | perl (<< 5.19) > > Fine by me, but that allows for perl 5.16 and lower, which have M::B < > 0.40. If that's not a concern, just drop the versioned part and use > plain libmodule-build-perl? Right. If that's a concern (it is to me, but some consider backporting irrelevant to support, and some favor automated dependency handling over most accurate declaration), then repeat with the lower limitation as well, but with the satisfiable-in-current-unstable listed first in both cases, like this: Build-Depends: libmodule-build-perl (>= 0.40) | perl (<< 5.19), libmodule-build-perl (>= 0.40) | perl (>= 5.17.1) - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
