The ebuild has been in tree since more than 3 months.
The new version fixes bug 511098, bug 511100 und bug 530636 (and
possibly also bug 511102).
On amd64 and x86 all dependencies are stable.
On ppc stabilization is more difficult: The new dependencies
sci-mathematics/flint, sci-mathematics/4ti2 and sci-libs/cddlib don't
yet have the ppc keyword.
There are still some QA warnings, but I think it is good to stabilize this version.
ppc stable. Closing.
