Apparently the dickhead maintainer of ndiswrapper-source has just gone into his shell and refuses to discuss this problem.
Since his package (and theoretically any package which generates packages) may be uninstallable because there is no way to say "give me the source and everything I need to be able to use the output" via Recommends, or a foo-source-end-user metapackage which depends on foo-source and foo-utils, we are left in the situation of not being able to trust that -source packages won't hork our system. (If the package is a network card driver source package our system may then be unfixable because now our network card is hosed). Given that -source packages do not adequately specify the dependencies to be able to use the output, one must NEVER run "dpkg -i" a given deb without first running "dpkg --dry-run -i" on the same debs and verifying that it returns a zero exit code. I don't know why this isn't the default behavior of dpkg -i, checking that at least all dependencies will be met before uninstalling old packages and leaving the system broken.
