Hallo!
your package-manager should handle the dependencies/conflicts correctly,
that is: ask you if you want to uninstall the "puredata" package when
you try to install the "pd-extended" package.as H-C said, it doesn't seem to happen. I only get the error message, and
no other options available.then it might be a bug in the package-manager, but not in the package.
The standard package manager (apt-get) on debian and ubuntu does not ask you if you want to uninstall the package - you have to uninstall it manually. Only aptitude is asking these questions ...
LG Georg
