gala/mutter dependency not available

[RobrVann]

As alluded in https://github.com/pimvullers/elementary/issues/207, gala looks to require up to libmutter-6. Current version of mutter provided by gentoo repo is >=mutter-40.2.1 (libmutter-8). Any chance this can get updated?

Officially, gala does not yet support libmutter-8. This is also due to the fact that EOS5 uses libmutter-2, and EOS 6 will use libmutter-6 (or 7, I don't remember) Work on supporting libmutter-8 is underway in the upstream, as soon as I update all the packages to the latest versions, I will try to update mutter as well, perhaps it will be possible earlier (while I have libmutter-7)

[Dirli]

If the process (adding libmutter-8 support) is delayed, I can add the gnome38 (libmutter-7) here for now, if it is relevant

[pimvullers]

gala for eos6 supports mutter-6/7/8 just added this to eos6 branch. But could not build yet, since I've been doing this from Gentoo Prefix on elementary OS6, and for prefix there are some issues in installing polkit. So I'll need to switch back to normal Gentoo to continue development on the ebuilds

[pimvullers]

Please try eos6 branch, this resolves the mutter dependency.

[pimvullers]

eos6 branch will be merged to master in coming weeks.
