When I run ./installer.pl -i: I get: MISSING PERL MODULES You are missing some Perl modules required by Koha. Please run this again after installing them. They may be installed by finding packages from your operating system supplier, or running (as root) the following commands: perl -MCPAN -e 'install "MARC::File::XML"' perl -MCPAN -e 'install "ZOOM"' perl -MCPAN -e 'install "You will need GD::Barcode for the new barcode generator"' perl -MCPAN -e 'install "You will need Net::LDAP if you want to authentify patrons through a LDAP"' running perl -MCPAN -e 'install "MARC::File::XML"' I get : Failed 4/4 test scripts, 0.00% okay. 29/34 subtests failed, 14.71% okay. make: *** [test_dynamic] Error 255 /usr/bin/make test -- NOT OK Running make install make test had returned bad status, won't install without force How do I get it to force install? I tried -f and it would not work. *** WARNING! ZOOM-Perl requires at least version 2.1.45 of YAZ, but is currently you only have version 2.1.8. Running make test Make had some problems, maybe interrupted? Won't test Running make install Make had some problems, maybe interrupted? Won't install I get the YAZ error but it should be correct
