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. Reproducible: Always
There are still some QA warnings, but I think it is good to stabilize this version.
amd64 stable
x86 stable
ppc stable. Closing.
