The above looks good. I don't think anything uses flex or bison. It *used* to be that Sage's build did (for Singular), but Gonzalo Tornaria removed that dependency. Is Latex still required? I can't think of anything it is needed for. I don't think it is needed to install Sage. It's useful in some cases when using Sage though.
