So. Gnumeric is the culprit. Is this resolvable? If, for example, I uninstall gnumeric and then reinstall libart followed by gnumeric, is gnumeric likely to accept this?
Is it possible to specify the repository I want apt-get to use for a specific install? (I suppose I could wget the version I want and then install from the local file.)
I get the point of "two versions of libart available". In the real world this is going to happen. But how do debian adepts deal with this sort of issue?
