Bug#752713: libtext-bibtex-perl: hardcodes /usr/lib/perl5

[Niko Tyni]

Package: libtext-bibtex-perl
Version: 0.66-2
Severity: important
User: debian-perl at lists.debian.org
Usertags: perl-5.20-transition

Starting with version 5.20.0 (currently in experimental), the Debian
perl package is changing the "vendorarch" library paths (currently
/usr/lib/perl5) to include the multiarch triplet and the perl version. See
#748380 for details.

For this to work, packages containing binary perl modules need to migrate
from using the hardcoded /usr/lib/perl5 directory to the value of the
$Config{vendorarch} variable, as defined in the 'Config' module.

This package fails to build with perl_5.20.0-1 from experimental:

     dh_install -a
  cp: cannot stat 'debian/tmp/usr/lib/perl5': No such file or directory
  dh_install: cp -a debian/tmp/usr/lib/perl5 debian/libtext-bibtex-perl//usr/lib/ returned exit code 1
  make: *** [binary-arch] Error 2
  debian/rules:4: recipe for target 'binary-arch' failed

One solution for this might be an executable debhelper install file
(available with debhelper compat level 9) expanding $Config{vendorarch}.
See #751924 for an example of this.

Please ask on the debian-perl list if you want help with this, and see
