sci-mathematics/maxima-5.37.3-r4 stabilised on amd64

[WPettersson]

Gentoo has stabilised maxima 5.37.3-r4 (see https://bugs.gentoo.org/show_bug.cgi?id=573544) but sage-on-gentoo only has 5.35.1-r2, which means I'm now getting

It's fairly easy for me to work around personally, but should something be done about this?

[kiwifb]

It doesn't prevent you from upgrading anything does it? I have lived with a version of that message for a while now. Nothing much you can do about it.

[WPettersson]

It does stop the upgrade from going through on my system, but I just masked sci-mathematics/maxima::gentoo and that ensures that I'll stick to the sage-on-gentoo version.

[kiwifb]

OK that's not normal, we should try to get to the bottom of that. What does equery d maxima report.

[WPettersson]

$ equery d maxima
 * These packages depend on maxima:
sci-mathematics/sage-7.2 (~sci-mathematics/maxima-5.35.1[ecls])

Just sage, it appears.

[strogdon]

The same here. I've had to mask =sci-mathematics/maxima-5.37.3-r4 to accommodate a recent system upgrade.

[kiwifb]

I have not been hit yet. It may be possible to move to a 5.38.1 build (with appropriate patches) I'll need a bit of time to investigate. In the mean time which version of portage do you have?

In my prefix I don't seem to have any conflicts.

[kiwifb]

Hum. Would removing it and then re-installing solve the problem?

[strogdon]

I presume you meant maxima. Removing portage is probably not a good idea. After removing maxima and re-installing and then unmasking version 5.37.3-r4:

In this latter case the merge proceeds. It was perhaps in the former case (sage not in world file) that I encountered the issue. I usually don't have sage in my world file, so this may not be what @WPettersson has.

[kiwifb]

Yes, you are not in the case where sage is the only dependency of maxima. It looks like you have imaxima and wxmaxima also present and complicating the mix. You may need a very specific version of wxmaxima to match your version of maxima if I remember well.

[WPettersson]

Uninstalling and reinstalling maxima does work fine on my system, so I can't reproduce this any more. It had been a month or so since I updated due to a recent move, that may have been part of the issue.

[kiwifb]

I think sometimes there is cached data from the current install that gets in the way. When you install something a "copy" of the ebuild and some cache data about the package are stored. It helps with removal in the future when an ebuild is not in the tree anymore and so forth. I think sometimes those cached copy can get out of sync with what happens in portage internally and causes these kind of issues.
