Hello Al-Modabber, You may find the following page on the Wiki useful. Ubuntu uses the same underlying commands as Debian so you should be able to open up a terminal and search for your prerequisites using the methods documented on this page; http://wiki.koha-community.org/wiki/How_to_install_missing_Perl_modules_on_D... I'm unsure whether you've installed CPAN or not as yet, but you may need to use it to obtain a number of said packages. This is a simple "sudo apt-get install cpan" followed by cpan and accepting the default settings during setup. Once you've installed the missing dependencies, you should re-run Perl MakeFile.pl and continue as before. Hope this gives you a good starting point. <http://wiki.koha-community.org/wiki/How_to_install_missing_Perl_modules_on_Debian> -- Martin Renvoize Software Developer, PTFS Europe Ltd Content Management and Library Solutions martin.renvoize@ptfs-europe.com skype: Martin Renvoize http://www.ptfs-europe.com
