The major problem is "bootstraping", and possibly "political" issues if you
need patches in other packages you do not maintain. Once you get it
working, usually updating to a newer sagemath is reasonably simple,
just don't let it rot for too long.
François know I did not look in my sage package for almost too months :-)
While I had some known doctest failures for very long due to using a
different version of some component, e.g. python, for several times I
found bugs that just did not trigger in sage due to it not using packages
outside its install tree.

Since the problem appears to be related to linbox, besides the patch
I suggested, maybe this can help:
