Zend Framework 1.6.0 deb packages for Ubuntu Hardy Heron will be available tomorrow from http://packages.havelsoft.org.
Feel free to use it on every debian based distribution. This package doesn't contains the externals and laboratory folders. I will maintain the package under my own control for the future releases of Zend Framework. The release cycles for the original package (Ubuntu) are very slow and the Hardy Heron distro has 3/5 years of support. Happy coding Mario
