My understanding is that you do not need to in this situation: the user explicitly asked to install a non-GPL-compatible software, so "he is assumed to know what he is doing". Apparently we only need a warning if the user installs a GPL-compatible software which (in sage) would trigger the installation of a non-GPL software that the user may not even notice. In this second case, we should make sure that he notices, for instance with an explicit confirmation.
