I see the conflict with app-accessibility/julius-4.1 and sci-libs/fplll-3.0.12-r2.
That's a pretty generic name for a binary...
> That's a pretty generic name for a binary... Indeed. Perhaps they both should prefix?
Fixed in -r3, 'generate' is now 'generate_matrix' which describes more closely what it does. I fixed it with --program-transform-name (thanks autootools).
this bugtracker is only for a) gx86 tree b) overlays hosted on g.o.g report here https://github.com/cschwan/sage-on-gentoo/issues besides, sci-libs/fplll-4.0.4 is in the tree and I cannot reproduce it with that version
That is an inappropriate closer. Gentoo has to coordinate these things in a central place, no matter where the overlays are hosted. Especially given that the two overlays here target moving toward inclusion in gx86. Also, the science overlay (on g.o.g) also has an ebuild for fplll, so this in fact is g.o.g vs g.o.g.
Both julius and fplll are already in portage. You seem to have missed that.
In the many days since I opened this, the sage overlay added a --program-transform-name to fix this in fplll 3, and then upstream renamed the executable for fplll 4. The bug was never invalid. But it did get fixed.
