Hi, Karl xecjk once worked fine without ctex installed. xecjk is a member of collection-xetex. However, since xecjk v3.8.3, it requires ctexhook.sty. Can you add a dependency on ctex to xecjk? I see ctex has a dependency on xecjk among others. Would such cyclic dependencies cause trouble in TeX Live? Regards, Akira
