Hi all,

sage-4.4.2 has just been released. I am guessing that Christopher
may be preparing for exams in June so I will probably do the bump.
I have already bumped sage-doc.

Other matters:
-The situation on amd64 is still bad. There has been a silent (no revbump)
update to cython to deal with a strict-aliasing problem:
http://bugs.gentoo.org/show_bug.cgi?id=294585
I don't have the hardware so I cannot check if it has an influence on our
problems but it is worth a try.

-python-2.6.5-r2 is going stable. sage is of course still shipping 2.6.4.
I have already put a "pickled" version of python-2.6.5-r2 in the overlay 
(2.6.5-r99). Apart from:  
http://github.com/cschwan/sage-on-gentoo/issues#issue/1
which needs to be fixed in sage (patch/suggestions welcome) I don't expect
any problems with that.

-mpir-2.0.0 entered the overlay, sage is actually still shipping 1.2.2.
Report problems as usual.

-I have tracked 2 other failing tests which are now working:
http://github.com/cschwan/sage-on-gentoo/issues#issue/8
http://github.com/cschwan/sage-on-gentoo/issues#issue/9

-I am wondering if issues 3 and 6 are down to -ffast-math in one way
or another. If you have any similar issues please post.

-still no clue on gap's behaviour. Considering the amount of aliasing problem
you may as well try to add -fno-strict-aliasing to your CFLAGS for building 
gap and see if that improve things.

-I have imported sympy-0.6.6 in the overlay as it has left the portage tree
and sage currently doesn't work with 0.6.7. We should investigate doing
some porting work. Porting work to scipy-0.7.2 would be a good idea too.

Francois
