@lanodan I thought I'll let you know that building Pleroma-FE on Gentoo is currently broken for versions 2.8.0 and 9999 after the switch from webpack to vite.
The culprit is the --no-bin-links flag to yarn install. It can't find vite when running yarn run build. (Probably because it's looks for it in the node_modules/.bin directory that doesn't get created with that flag specified.)
