Can't install in Hardy

I have Ubuntu Server Hardy (8.04.2) which came from a custom-install from the eBox Platform. When I try to install SchoolTool, I receive the following error:

root@ebox:/etc/apt# apt-get install schooltool-2009
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  schooltool-2009: Depends: schooltool-common but it is not going to be installed
                   Depends: python-schooltool but it is not going to be installed
                   Depends: python-schooltool.stapp2008fall but it is not going to be installed
                   Depends: python-zope.server but it is not going to be installed
E: Broken packages
