Hello, I have updated ocamlgsl 1 week ago because there was an RC bug on it (#309844). The correction is pretty trivial (only need to depends on libgsl0-dev). Diff between testing/unstable are about 5 lines long. Could you update the testing package to remove definitively the RC bugs? Thanks Regard Sylvain Le Gall ps: could you CC-me, i am not subscribe to debian-release list
