Was doing a fresh install of what I pulled from the git repository a couple days ago. I am running Ubuntu 12.04 libdatetime-format-mysql-perl was missing after I did something similar to : apt-get install `./install_misc/ubuntu_pkg_check.sh | grep none | cut -f1 -d' '` I then did a ./koha_perl_deps.pl -m It said DateTime::Format::MySQL (the capitalization may be off, I'm doing this from memory). So I did: aptitude search datetime-format-mysql And such a library existed, so I installed it. And the koha_perl_deps.sh didn't complain about anything missing. I figure it is a quick one-line add. I confirmed that libdatetime-format-mysql-perl also exists on Ubuntu 10.10 Though, I was noticing the ubuntu.packages still references yaz3. The current version is yaz4. yaz3 does not exist on 12.04, nor 10.10. Please change libyaz3 and libyaz3-dev to libyaz4 and libyaz4-dev.
A similar problem was also dealt with in bug 8489. *** This bug has been marked as a duplicate of bug 8478 ***
