Bug#977512: src:libconfig-identity-perl: Build-Depends on old gnupg1, but could use gnupg2

[Chris Hofstaedtler]

Package: src:libconfig-identity-perl
Version: 0.0019-1
Severity: normal

Dear Perl Maintainers,

a very long time ago, Build-Depends were changed so gnupg1 is explicitly
used, due to CPAN RT#112569. However, upstream has apparently fixed the
tests in 0.0019 - this is noted in the same RT bug.

Please consider switching the build dependency to gnupg2.

Chris
