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.
