Hello, I am the maintainer of aur/sage-mathematics. I think this package has matured to the point where it could be included into the community repository. There are no issues with this package that I am currently aware of. Its inclusion into community would probably save a lot of compilation time for everyone. The namcap and built package could be found at: http://pkgbuild.com/~td123/ The package is ~700MB per architecture. I didn't modularize this package because upstream doesn't intend to modularize it, and because of the amount of work that would require, not only to split everything off, but to make sure nothing breaks at the same time. Case in point, http://github.com/cschwan/sage-on-gentoo I would like to start discussing its inclusion now. Cheers!
