Hi all,
so it's that time again where I look at how "easy" it would be to update
various pieces of sage to the latest upstream. The tests were performed
on a linux machine running in 64 bit (amd64) based on 4.6.2.alpha2.
numpy-1.5.1: upgrade quite nicely, just two doctests broken by a new warning
from numpy:
sage -t -force_lib "devel/sage/sage/calculus/interpolators.pyx"

"/home/gnuke/gentoo/usr/share/sage/devel/sage/sage/calculus/interpolators.pyx",
line 52:
sage: m = Riemann_Map([lambda x: ps.value(x)], [lambda x:
ps.derivative(x)],0)
Expected nothing
Got:
doctest:1: ComplexWarning: Casting complex values to real discards the
imaginary part

Harmless and easy to correct.
ecl-11.1.1/maxima-5.23.2
Lots of numerical noise and a bit of formatting. Mostly due to ecl as
downgrading maxima to 5.22.1 but keeping ecl-11.1.1 doesn't change the results
of the tests. 6 files are affected in total.
gfan-0.5: that's very bad.

The command "gfan" is deprecate for computing all Groebner bases of an

And it goes on as almost every single test in that file fails... 4 files

mpfi-1.5: a number of tests fail in interesting ways:

Nothing much to say there. But as possible consequence of these
sign flipping we also have these failures:

I should also mention that sage works well with mpfi-1.4
