Coq, or actually coqide, failed to build due to retirement of gtksourceview2: https://koji.fedoraproject.org/koji/buildinfo?buildID=1358366 We may have to revive gtksourceview2 or update Coq to the 8.10 branch, which uses Gtk3 with LablGtk 3. Both Coq 8.10 and LablGtk 3 are still in Beta state. And reviving gtksourceview2 is not difficult.
gtksourceview2 has been brought back, and coq has been built in Rawhide. I'll keep an eye out for coq 8.10.
F31 ocaml-lablgtk may be also required to rebuild.
Already done, and waiting for karma + the end of the Beta freeze: https://bodhi.fedoraproject.org/updates/FEDORA-2019-7173d1702d
