josephgbr [1] filed a deletion request for gnome-builder [2]: Since GNOME 3.16 release in Arch, gnome-builder version 3.16.2 is available in [extra] repository. Since then, I believe this package in aurweb is redundant and deprecated. [1] https://aur.archlinux.org/account/josephgbr/ [2] https://aur.archlinux.org/pkgbase/gnome-builder/
