emerge --update --deep @world

試したこと

「gentoo ERROR: gnome-base/gnome-shell-40.3::gentoo failed」などで検索してみましたが、解決できませんでした。

StackOverFlowに似たようなエラーについての投稿がありましたが、有益な解決策は載っていませんでした。
https://forums.gentoo.org/viewtopic-t-1099070-start-0.html

https://bugs.gentoo.org/795471のページで

emerge --sync
emerge -avujDN --with-bdeps=y --autounmask-write=y @world

emerge -1 dev-libs/gjs

の記載があったのでそれぞれ実行してみたのですが、改善しませんでした。

同じページで「libgjs」の再構築で解決しました、との記載があったので

emerge libgjs

を実行し、

emerge: there are no ebuilds to satisfy "libgjs".

emerge: searching for similar names...
emerge: Maybe you meant any of these: media-libs/libjsw, gnome-extra/libgsf, dev-java/libg?

となったので

emerge media-libs/libjsw
emerge gnome-extra/libgsf
emerge dev-java/libg

をそれぞれ実行してみましたが、改善しませんでした。

補足情報（FW/ツールのバージョンなど）

Windows10にVirtualBoxでGentooをインストール

Host: Windows10 Home
Guest: Gentoo Base System release 2.7
