Bug#784137: perl-modules : Depends: perl-base (>= 5.20.2-3+deb8u1) but 5.20.2-3 is installed

[Gilles Mocellin]

Package: perl-modules
Version: 5.20.2-4
Severity: normal

Dear Maintainer,

On Jessie, I can't upgrade perl-modules because of a laking dependency on
perl-base :
~  LANG=C sudo aptitude -s full-upgrade
The following packages will be upgraded: 
  perl-modules{b} 
The following packages are RECOMMENDED but will NOT be installed:
  libarchive-extract-perl libcgi-pm-perl libmodule-build-perl libmodule-pluggable-perl libpackage-constants-perl libpod-latex-perl libterm-ui-perl 
  libtext-soundex-perl 
1 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 2551 kB of archives. After unpacking 0 B will be used.
The following packages have unmet dependencies:
 perl-modules : Depends: perl-base (>= 5.20.2-3+deb8u1) but 5.20.2-3 is installed.
The following actions will resolve these dependencies:

Ah, I just see that : I have jessie-proposed-updates in my sources list, and there is only a perl-modules update, not perl-base...
