This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
Zotero breaks every time firefox is updated (about every six weeks). It
is always fixed with the next zotero update, but that can take weeks.
Sometimes, upstream even skips firefox releases. This will stop zotero
breaking every time.
