Restricting the version to something below 1.1.5 in libX11 should help here.
Those versions are indeed incompatible libX11 1.1 should go with xproto <=7.0.14, libX11 1.2 should go with xproto 7.0.15. We did try putting blockers and restrictions in X packages, but with the recent churn in headers, this just proved impossible to express sanely without ranged deps. And since this particular feature has always been rejected, we just gave up. So yeah, just upgrade everything to the latest stable _or_ ~arch (don't try to mix if you're not sure) and it'll work correctly. Thanks
