Yes. When a package has been modified in Ubuntu, next time when Debian
updates the package a manual update is required in Ubuntu and the
package maintainer needs to decide if the Ubuntu changes are still

The package was last built in jaunty. It is not built in karmic
because the source has not been updated.

If you wish that graphviz should be built against latest ocaml in
