Hi, Just in case you did not think of it, you need to modify dependencies and build dependencies with respect to 3.07-versioned of those dependencies. For exemple, a program which build-depends on lablgl, needs to build-depend on lablgl (>= 0.99-16). We currently have to mean to ensure the consistency. Cheers, PS: I've prepared ocamlsdl but I need its dependencies to be available on powerpc before uploading it. -- Jérôme Marant
