Hi all,
I should say first that Christopher deserve most of the credit for the
recent push.
As for Gentoo/Prefix port, I am thinking about looking at it on a mac OSX
machine (10.5 at the moment) as I have access to one. It is, as always, a
question of time.
As to emphasize Christopher request on other points it would be nice
to have SQLalchemy, networkx, cvxopt updated (I know the last one
may be an issue).
As for the question of the test... Well we do have some failures - some are
expected, for example some of the maxima tests actually check where some
maxima files are installed, same with cython (also there is a formatting issues
as well for cython).
We are using a more recent cvxopt, which leads to formatting issues in the
output but this is a known problem.
Now for the serious stuff as we need to figure what's going wrong at some stage
so here are some of our failures:
