While it is true that Debian's tools to manage repositories only allow a single version of a package to exist within a given Packages file, it is absolutely not true that you cannot generate a Debian package repository that contains multiple versions of a package (within the same Packages file). Many external repositories do this, and it seems to work just fine; "apt-cache show <package>" on such repositories will list all the various available versions. I believe apt will deal with the above problem just fine. It would install 2.0-43. -- It is easy to love a country that is famous for chocolate and beer -- Barack Obama, speaking in Brussels, Belgium, 2014-03-26
