Greetings, As I already hinted before, don't use CentOS 5.x, use CentOS 6.x! And also, compile from source: http://ftp.indexdata.dk/pub/zebra/redhat/centos/6/SRPMS/idzebra-2.0.55-2inde... You are causing yourself a lot of headaches trying to shoehorn a newer version of Koha which requires perl 5.10 into an OS which has perl 5.8 by default. Not to mention the headaches you are having trying to get the dependencies. CentOS 6.x is still painful for the dependencies, but it is more likely to succeed, since there are wiki pages for it. And if you have the ability, choose Debian, Ubuntu, or some other Debian-based Linux variant. http://wiki.koha-community.org/wiki/Debian http://wiki.koha-community.org/wiki/Koha_on_ubuntu_-_packages Again to summarize: - Use CentOS 6! - Compile from source GPML, Mark Tompsett
