The build for x11-toolkits/gtk-layer-shell with DOCS option set fails with the following message:
Building documentation for gtk-layer-shell
ERROR: Error in gtkdoc helper script:
ERROR: ['/usr/local/bin/gtkdoc-fixxref', '--module=gtk-layer-shell', '--module-dir=html', '--html-dir=share/gtk-doc/html', '--extra-dir=/usr/local/share/gtk-doc/html/glib', '--extra-dir=/usr/local/share/gtk-doc/html/gobject', '--extra-dir=/usr/local/share/gtk-doc/html/gio', '--extra-dir=/usr/local/share/gtk-doc/html/gtk3'] failed with status 1
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/bin/source-highlight': '/usr/local/bin/source-highlight'
^Triage: Reporter is committer, assign accordingly.
The issue should be solved by r543973, however also a textproc/gtk-doc rebuild is required after textproc/source-highlight removal.
