Hi Two additional comments:
These packages depend on dune-common, dune-geometry, dune-grid, dune-istl, for which Debian is currently uploading new versions to experimental. Therefore I have also tested the build with the dune packages from experimental. If it is more suitable for you to have RFS for each individual package, I will gladly do that. The intention of just one ITP and RFS bug was to make clear that there are dependencies between these packages. Regads, -- Markus
