Sorry Dave, no spkg. I did everything so far at the system level and then
tested the doctests in sage-on-gentoo. It was quick and easy for me to do
that. I attached the patch to ecl in #10766.
If you want I will do a spkg but I will have to ask Minh to have access to
his google code repo as I don't have my own web space unfortunately.
I'd like to discuss more the last doctest that I ended up patching separately.
The whole section tested reads:
Check if #6189 is fixed (which, by the way, also
demonstrates it's not always good to expand)::
sage: n = N; n
<function numerical_approx at ...>
sage: F(x) = 1/sqrt(2*pi*1^2)*exp(-1/(2*1^2)*(x-0)^2)
sage: G(x) = 1/sqrt(2*pi*n(1)^2)*exp(-1/(2*n(1)^2)*(x-n(0))^2)
sage: integrate( (F(x)-F(x))^2, x, -infinity, infinity).n()
0.000000000000000
sage: integrate( ((F(x)-G(x))^2).expand(), x, -infinity, infinity).n()
-6.26376265908397e-17
sage: integrate( (F(x)-G(x))^2, x, -infinity, infinity).n()
0
Now the two computations gives the same result, independently of the
version of maxima (5.22.1 and 5.23.2) and that's not 0.
It looks like this version of ecl reopen #6189.
Comments anyone?
