Busy upgrading to 16.05 at the moment, and have noticed an issue with Business::ISBN. Here on Fedora (using my KohaExtra repository: dnf copr enable vanoudt/KOHAExtra ) Business::ISBN is at version 2.010. That's a 10 at the end, as opposed to a 5 which the required version (2.05) asks for. It's a weird numbering scheme, but the changelog shows that 2.010 is actually a later release than 2.05 . Naturally, koha_perl_deps.pl tells me that this module requires updating... but it doesn't. Not sure what the right fix here is...
This is related to Bug 5599 - koha_perl_deps.pl and PerlDependencies.pm don't compare $VERSION numbers correctly. To get more information in such cases, I introduced Bug Bug 12790 - Perl modules: Display required version numbers on about page Bug 5599 got a temporary fix for Graphics::Magick - 'min_ver' => '1.3.5' + 'min_ver' => '1.3.05' This is a similar case (2.05 vs 2.010). There are other issues waiting, e.g. File::Path (2.07) 2.08_01 (compares correctly at the moment, but what about something like 2.08_01 vs 2.09 ?) Maybe the following helps to get a sustainable solution: http://stackoverflow.com/questions/19973852/perl-compare-version-numbers-5-1-5-10 Answer 6: print version->declare('5.1')->numify; # 5.00100 print version->declare('5.10')->numify; # 5.01000
