latest mono packages are broken

[Nadeem Bitar]

I've installed mono before on hoary with no problem but I've tried to
do it today on a different machine and it's broken.

 mono: Depends: mono-jit (= 1.0.4-1) but it is not going to be installed or
                 mono-mint (= 1.0.4-1) but it is not going to be installed
        Depends: mono-utils (= 1.0.4-1) but it is not going to be installed
        Depends: mono-assemblies-arch but it is not going to be installed
