In the course of importing Koha 3.4.2 into the NetBSD pkgsrc collection, I tried to sort out the required Perl modules. I compared a hand-crafted list (obtained by grep'ing) with C4/Installer/PerlDependencies.pm and it looks like I've found some mis-matches. 1. The following modules are listed in $PERL_DEPS, but I can't find any place where they are actually being used: DBD::mysql DateTime Email::Date GD::Barcode::UPCE PDF::API2::Simple PDF::API2::Util XML::RSS 2. The following modules are NOT listed in $PERL_DEPS, though it appears to me they are, in fact, used (maybe in dead code?) in the listed file(s): Archive::Zip C4/ImportExportFramework.pm Cache::Memcached C4/Auth.pm, C4/Cache/Memcached.pm File::Slurp misc/load_testing/benchmark_webservices.pl HTML::Entities C4/Acquisition.pm, C4/ILSDI/Services.pm HTML::Tree misc/translator/text-extract.pl HTTPD::Bench::ApacheBench misc/load_testing/benchmark_circulation.pl MARC::Lint misc/cronjobs/MARC21_parse_test.pl Mail::RFC822::Address misc/cronjobs/smsoverdues.pl SQL::Statement C4/ImportExportFramework.pm Test::Class::Load t/db_dependent/database_dependent.pl Test::Exception selenium/PERL/Members/FilterMembers.pl, selenium/PERL/Members/AddMember.pl, selenium/PERL/Members/Searchmember.pl Test::WWW::Selenium selenium/PERL/Members/FilterMembers.pl, selenium/PERL/Members/AddMember.pl, selenium/PERL/Members/Searchmember.pl Unix::Syslog misc/bin/zebraqueue_daemon.pl Win32::Process sms/sms_listen_windows_start.pl 3. The following CORE modules are listed in $PERL_DEPS. This may be intentional: CGI::Carp Digest::MD5 Digest::SHA File::Temp Getopt::Long Getopt::Std IPC::Cmd List::Util Locale::Language MIME::Base64 MIME::QuotedPrint POSIX Storable Term::ANSIColor Test Test::Harness Test::More Text::Wrap Time::HiRes Time::localtime Unicode::Normalize 4. It appears to be inconsistent whether $PERL_DEPS lists the modules actually use'd or require'd (i.e., ZOOM) or those modules' base modules (i.e., Net::Z3950::ZOOM). Thanks for any clarification.
