This is no longer an application I utilize.

I guess your removal could've waited a few days...

For now, we can use media-libs/mesa present within the
Asahi Linux overlay. It has been added once again with
custom patches.

This manually applies https://gitlab.gnome.org/GNOME/evolution/-/commit/9e3019a0961e91e5fbffe190b973a47c7fafd361
which updates Evolution to utilize API changes for gnome-desktop 43.0.

This should be safe to revert and resolv whenever GNOME 43.0 becomes more
stable on Gentoo.

Eventually, this will not be necessary.
However, upstream Gentoo is currently holding out
until the Asahi drivers make it upstream:
