Hi all,

A few items about what's happening or not in sage-on-gentoo.

-First as Denis said please do come and discuss your problems
here! It will get a bit more exposure than sending an email to 
Christopher or me (even if eventually we tell each other about it).

-The notebook (aka web interface) is currently broken we haven't
figured out why yet. Downgrading twisted to version 8.x doesn't
solve the problem. We may have to test the previous version to see
if that works - may need to touch sage's ebuild to allow it - if 
anyone is adventurous enough I'd be grateful for the testing.
While the notebook is broken the cli and cantor (kde-base/cantor)
works.

-Christopher has exams coming in the next 2 weeks. Be gentle.

-Until recently we had mpir in the overlay (both science and sage-on-gentoo)
but we weren't actually using it. sage ship mpir and install it in gmp 
compatibility mode - that is it provides gmp.h and libgmp and sage packages
links against these instead of mpir directly. No porting to use mpir natively 
has been done in sage.
Therefore while we were shipping mpir, gmp was actually used.
Recently I have updated sage-clib to use mpir, so far it seems to be working.
I have introduced a mpir use flag and ported a few ebuilds to mpir. Beware that 
it is a work in progress and enabling the useflag may cause breakage of sage
and may be other apps. Testing welcome nonetheless.

That it for now.
