Hi VuLK,
unfortunately at this stage we do not support that in sage-on-gentoo.
Actually the version we ship is stripped down in some ways.
Let me explain:
sage has its own upgrade system, it wouldn't work in the kind of
installation we
do and that would mean changing, adding and deleting files in the
system outside
the control of the package manager. We definitely don't want to do that. So we
removed the options for sage upgrade. The only option to upgrade is
portage/package-core etc...
There are options to help you create spkg, install spkg and so on, we could
probably give back the one to create spkg but we otherwise completely
circumvent the sage build system so the corresponding options are gone.
The main problem is that sage's normal distribution model is trying to be
developer friendly but isn't distro friendly. We coerced it into a
distro which
makes it more appealing for an end user to try but it is stripped of
some of the
dev-friendly features.
There are advantages and disadvantages for both models. We can be/are
more up to
date than sage with some packages. If I patch something I literally have to
reinstall the whole of of the sage spkg from portage, the equivalent of sage
-ba while from vanilla sage you could use sage -b and only rebuild the
necessary bits.
Now you are the first person making this kind of request about using something
like the combinat queue. We probably can give you an ebuild pulling the
combinat queue. There are just two caveats here:
1) it may take a bit of time for us to come up with something.
2) because I expect the queue to be somewhat in flux it would have to be a hot
ebuild of some kind. If you can live with that we can probably work something
out.
