I'm currently at the Formal Power Series and Algebraic Combinatorics
(FPSAC) conference, which is a major annual conference for, well, the
algebraic combinatorics community. Earlier today I realized how quickly
Sage has grown in this community:
In 2007, Sage was not on the radar at all at FPSAC.

Hi Fredrik,
Here's a simplistic way that doesn't involve cloning or queues.
Compile Sage from source on your machine and wrap up a binary for that
machine with
$ ./sage -bdist x.y.z-description
The resulting binary then appears under SAGE_ROOT/dist/. Copy/move
that binary to somewhere safe so
Hi,
our work with sage-on-gentoo has seen great progress - we are now able
to supply fully working and recent versions of Sage which live in /
usr. We did this (among other things) by setting

SAGE_ROOT=/usr/share/sage
This enables Sage to put all scripts and binaries into

The problem is that in Sage's sources and scripts $SAGE_ROOT/local

There are six python files which would need a patch and more than five

The single biggest improvement in my mind would be made to MPIR. And I
know the MPIR devels would absolutely love to have them contribute.
Jason and Brian have been working very hard on simplifying MPIR so
that it can be more easily modified.
There are some instances in flint that would benefit.

by the way, storing sage on a FAT32 partion was the main problem.
Therefore, never keep sage on FAT32
