After succesfully (and without any problems) having upgraded koha to 3.8.0 from 3.06.04 on my dual booted laptop I attempted to do the same on the main machine, both running Debian Squeeze. Doing the regular $ ./koha_perl_deps.pl -u -m it came up with the following list (and an error, but that does not seem to be an issue); [Sun Jun 3 12:17:35 2012] koha_perl_deps.pl: Use of uninitialized value $version in numeric lt (<) at /usr/local/share/perl/5.10.1/Modern/Perl.pm line 25. [Sun Jun 3 12:17:35 2012] koha_perl_deps.pl: Use of uninitialized value $version in numeric lt (<) at /usr/local/share/perl/5.10.1/Modern/Perl.pm line 25. Installed Required Module is Module Name Version Version Required -------------------------------------------------------------------------------------------- DateTime 0 * 0.58 Yes DateTime::Event::ICal 0 * 0.08 Yes DateTime::Format::DateParse 0 * 0.04 Yes DateTime::Format::ICal 0 * 0.09 Yes DateTime::Set 0 * 0.28 Yes DateTime::TimeZone 0 * 1.26 Yes XML::RSS 0 * 1.31 Yes -------------------------------------------------------------------------------------------- Total modules reported: 7 * Module is missing or requires an upgrade. So I start doing the cpan magic, and while initially this list was getting shorter (I was down to 3 or 4 missing modules) it suddenly returned to the 7 missing modules. Huh? I installed/updated all 7 modules, but it does not seem to matter; Trying to do a sudo cpan DateTime::Set for example, results in DateTime::Set is up to date (0.31), and so for all the modules; they are either the required version or higher. The only module that did not install easily was XML::RSS, which I had to install with -force $ ./koha_perl_deps.pl -u -m keeps insisting that they are missing or require an upgrade... Trying with the courage of the desperate to run $ perl Makefile.PL --prev-install-log /usr/share/koha/misc/koha-install-log results in the following: Can't locate Data/OptList.pm in @INC (@INC contains: /home/biblios/Downloads/koha-3.8.0 /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at /usr/local/share/perl/5.10.1/Class/Load.pm line 8.
