User brinleyang on Zend forums has posted a temporary fix for the bug Zend introduced in their server on Ubuntu 12.04.

What he did is he created a quick hack and removed the dependency on libkrb in libpq and php-5.3-imap-zend-server deb packages and manually installed the packages after which installing zend server ce should work.

However, this will most likely break postgres and imap zend modules so it may not be the solution for people who require those modules.
