• Since that is probably more work than you would like just to use it, I think you should be able to use a separately downloaded Scipy from within your Sage by importing it. I'm not quite sure where it would have to live, nor whether you'd have to name it something different. But since Sage is essentially Python-based, you could at least try sage: sys.path.append('/path/to/my-scipy-dir'); import my-scipy or something like that. If this is totally wrong, undoubtedly someone will let me know.
