Thanks to those who pointed me to the package "equivs" which, as far as I understand, cannot help in my case (version conflicts).
But to answer my own question: > So, is there any way to cheat apt, so that it accepts some broken > dependencies - because they are hidden from it? You can do so by editing /var/lib/dpkg/status and (necessary?) /var/lib/dpkg/available and preventing apt access to the original information about the concerned package. Surely not recommended - but does the trick :-) Andreas Goesele
