Looks like it's the only package in the tree still RDEPENDing on it, but I have seen that art-sharp is not even supplied on Debian and Fedora, is it really required? Thanks Reproducible: Always
# emerge --depclean art-sharp Calculating dependencies... done! dev-dotnet/art-sharp-2.24.1 pulled in by: dev-dotnet/gconf-sharp-2.24.1 dev-dotnet/gnome-sharp-2.24.1 gnome-extra/gnome-do-0.8.3.1 Looks like these dependencies are handled through gtk-sharp-module.eclass. If there are versions of gconf-sharp and gnome-sharp that no longer need art-sharp I'd be happy to check if gnome-do really still needs it.
You are true, this is because our splitting. Sorry for the noise
