Hi, I can see in the changelog of the Ocaml NMU: -=-=-=-=- Changes: ocaml (3.06-6.1) unstable; urgency=low . * (NMU) recompile at maintener request -=-=-=-=- I'm sorry but such explainations are not satisfactory. More info should be provided in order to explain the reasons for recompiling and what it is meant to fix. Please think of this next time. Thanks. Cheers, -- Jérôme Marant http://marant.org
