Well, binary version *IS* binary version. We consider the JVM as
mandatory for this binary version so we provide it. Your remark also
apply to blas / lapack implementation. We ship the original
implementation, which is far less performant than more modern ones
(ATLAS, GOTOBlas, MKL) *BUT* if someone wants better performance, then
compile a specific scilab version with specific dependencies.

This is package maintainer job (distro responsibility) to provide this
version not upstream one.

We guarantee software useability on the binary version. If you install
something with a package manager, fill any bug on distro bugzilla. If
you are able to reproduce on binary version, fill a bug on scilab BZ.
